(which was rebuilt 10 

years ago and has all of the pollution control stuff removed) and he
rebuilt/recurved my distributor. I am only now realizing the performance
gains I should have gotten when the motor was rebuilt. It runs like a
scalded cat and, best of all, the persistent miss I had between 2400 - 3000

I can now toddle around at 55 mph in 4th gear and not have to downshift.

When I saw Jeff at the BMTA Conference, I encouraged him to come down to THE
MITTY for Kastner Cup and the MG/TR show. He seemed enthusiastic about coming
down.

If he is able to get away, this would be a good place to discuss your
distributor needs.

So many times engines get rebuilt and the distributor gets left behind.

We think our recent Advanced Distributor rebuild was worth at least one second
per lap at Blackhawk Farms.

BTW, the VTR and the FOT will have complimentary event posters for VTR members
and Kas will be available to sign them.

we do a conversion of the original distributor with the electronics of the 123ignition. No electric tach needed with this conversion, the good old mechanical one works as it has used to work for decades. Just wanted to let you know.

Message-ID: <4F7F13BE.6070008@bright.net>

Good morning List. Some items of interest. Mike Cook, author of several 
TR books, longtime Triumph, British Leyland and Jaguar PR person and all 
around very knowledgeable good guy will be joining us. Mike will be 
wandering around shooting pictures, renewing old acquaintances and 
meeting new friends.  Mike is a very valuable resource to the Triumph 
community.  He was there when it started, including the US Competition 
Department.  Mike will be available at our booth several times during 
the week-end. Stop by and see Mike. Find out what it was really like "in 
the day" from one who was there from the start.  Bring your questions.

Also joining us, all the way from the UK, are John & Susanne Clancy.  
John is a videographer who has produced several Triumph DVD's. These 
will be available at our booth. The series of Triumph DVDs came about as 
a result of John Clancy's long term project to make a documentary of the 
history of the TR7 and TR8 series of cars.  When initially released in 
2007 it proved to be so popular the initial batch of pressed discs sold 
out within six months.  As a result further Triumph productions were 
undertaken -- first of all the Triumph Stag, then the Spitfire and GT6, 
the traditional TRs, the pre-war cars and others.  Currently a complete 
Triumph history is being compiled focusing on the saloon (sedan) models 
issued by the company plus 'California Air' featuring Kas Kastner and 
the US competitions department - this release is why John and his wife 
Susanne will be attending the Mitty at the end of the month to film some 
of the cars to help illustrate the story of why Triumph was so 
successful in America.
John has interviewed many former Standard-Triumph engineering and 
styling personnel and you will find many of these appear within each of 
the DVDs.  No one else currently making classic car documentaries goes 
into so much detail which makes these Triumph collectibles fairly unique 
and as time goes on we expect them to become quite historic in their own 
right.
Further details and previews of each title can be seen at 
www.triumphdvd.co.uk

We will be at the Mitty with our vendor trailer with both parts and 
regalia. We will have our gear reductions starters, steel braid brake 
hoses, suspension parts, rebuilt calipers,  etc.  If anyone needs "heavy 
items" - heads, gearboxes, engines, etc, we can bring these along - free 
freight is good!  Please let me know any requests as soon as possible so 
we can be sure to get it loaded. Our vendor trailer - white, flip open 
sides, along with an EZ-Up tent will be up on the hill in vendor area.

FOT and Kastner Cup shirts can be picked up at the trailer. Please try 
and pick up your shirts by Saturday afternoon.  Not sure what time we 
will be packing on Sunday to leave.  At the event you can reach me on my 
mobile - 419/230-9008. Mobile does not work in our building so please 
use any of the numbers listed on the signature line of this email for 
orders.

Thanks for your time and support. Ted

Hi guys,

Maybe some of you have a remedy for a problem that annoys me. 

When my engine is at operating temperature, the car will buck several times
when applying part throttle, under load, in 3rd, 4th or overdrive. It does
not do this when cold, nor if I down-shift. The carbs were re-built by
Paltech last year - air valves don't seem to be opening prematurely and I
have the proper oil in the dashpots. The plugs (clean), cap and condenser
are newer, wires OK, points clean, new rotor installed. Timing is dead on at
12BTDC when the retard is plugged off. Stock cam/exhaust and 10.1
compression - recent cylinder head rounding/polishing to eliminate pinging
(which it did). 

Any ideas out there would be greatly appreciated.

My TR6 is pinging after a high performance rebuild, and I can't stop it. 

 

I've done lots of things (high octane via xylene, retarded ignition, colder
plugs, richer mix) but it's starting to look that either the machinist
screwed up the head, or I've just built a monster.

 

I had a few specific questions:

 

1.      Cranking compression. The engine was built to 9.5:1 specs,
45.6cc/chamber. My cranking compression hot is 195 +/-5 psi with a Goodparts
GP-2 cam, which strikes me as 10-15 psi high. Anyone else have a comparison
of nominal CR vs. compression with a similar cam?

2.      Timing. Jeff at Advanced Distributors does great work, but he
refuses to tell me what specs he built my distributor to, which is not
helpful. Does anyone have experience with the 123 Distributor, which allows
the timing curve to be manipulated? Is that distributor compatible with the
MSD 6 series ignition?

 

Thanks for your help. If I hadn't used forged pistons, I'm sure I'd have
blown a ring land by now.

 

Cheers, Tom

Hi,

As a point of reference, I have a similar setup on my street car and I 
also have a race motor with a lot higher compression ratio. The static 
compression in the 9.67:1 motor is in the 195-200 range. That's with a GP3 
cam. The 12.3:1 motor compression is more like 245 lb.

Regarding your pinging, you should verify TDC is correct. You might be 
chasing your tail if the ring on the harmonic balancer has slipped and we 
all know that DOES happen from time to time.

On both my motors, I run 10 BTDC at idle and I have a total of 33 degrees 
advance (so the dizzy gives me 23 degrees on top of the 10 static).

No pinging on either motor, the street caar get 93 octane, the race car 
gets 110 octane race fuel.

Let me know if this is helpful.

regards,
rml

I used the GP-2 cam in our TR-6 when the previous cam lost a couple of
lobes. I had the head milled to bump compression up to approximately 8.8 or
8.75:1. No indication of any pre-ignition but I generally do use 93 octane
fuel.

Rob,

Always good to hear your advice.

I had my damper rebuilt as part of the engine rebuild by the "damper dudes."
I'm inclined to believe that the marks are correct: it idles sweetly at an
indicated 10-12 BTDC, manifold vacuum starts to drop off above that, and
when I retarded it to an indicated 4BTDC, my header wrap was smoking and my
idle exhaust CO went to 10%. 

You have 9.67:1, a GP-3, and only 5 psi more than me. I may be a little high
then, or it might just be testing conditions and compression gauges
providing the variation.

May I ask what you use for timing/ignition on that car?

I have a spare distributor on the shelf set up for 0 advance at idle and a
full 13 distributor/26 crank degrees at 2800 RPM. The car was pinging with
that distributor when I contacted Jeff, so I assume the one he built me is
milder, but I'm just guessing there.

Good writing is like a windowpane.

Brian---Too many possibilities here to list, so let's do the easiest ones to check or change first.
Your symptoms could be either ignition or fuel related. Weak spark will generally show up when the engine is under load, at the lower rpms. The higher compression you have makes this more likely. You can try different points gaps from the std. .015, going to a =/- .005 for testing purposes. A more costly but effective alternative would be a CD ignition, such as the MSD6A, along with their (in-cockpit) timing control.

On the fuel side of this, try a heavier oil such as 20W50 in the dash pots. This oil viscosity comes into play below 3,000 rpm. If this doesn't help, raise the needle assy. a half turn on each carb., going to the maximum lift, if necessary.
As I said, you can always go back to the original settings if none of the above help. Write back!

Dick

I put a 123 distributor on my last TR3 and it worked a charm.  

I have one in my recently-finished fast-road TR250 and it seems to be fine.
I will be putting the car on a dyno in a couple of weeks, so we'll probably
vary the settings then for maximal performance.

Subject: [6pack] Pinging Engine

My TR6 is pinging after a high performance rebuild, and I can't stop it. 

 

I've done lots of things (high octane via xylene, retarded ignition, colder
plugs, richer mix) but it's starting to look that either the machinist
screwed up the head, or I've just built a monster.

 

I had a few specific questions:

 

1.      Cranking compression. The engine was built to 9.5:1 specs,
45.6cc/chamber. My cranking compression hot is 195 +/-5 psi with a Goodparts
GP-2 cam, which strikes me as 10-15 psi high. Anyone else have a comparison
of nominal CR vs. compression with a similar cam?

2.      Timing. Jeff at Advanced Distributors does great work, but he
refuses to tell me what specs he built my distributor to, which is not
helpful. Does anyone have experience with the 123 Distributor, which allows
the timing curve to be manipulated? Is that distributor compatible with the
MSD 6 series ignition?

 

Thanks for your help. If I hadn't used forged pistons, I'm sure I'd have
blown a ring land by now.

 

Cheers, Tom

Interesting you would ask this question.  A few years backI had a bucking 
problem at low rpm's under light load. I did all you did below and 
discovered that by installing new air filters the problem vanished.  Easy 
solution.  Fast forward a few years and the bucking and jerking increased 
until the car was literally undriveable.  In the past 4 weeks I have 
replaced: ignition wire, plugs, rotor, condenser, points, dizzy cap, dizzy 
ground wire, fuel pump, fuel filter--all to no avail.  I then dismanteled 
the Zenith carbs and checked the floats for proper settings, and checked 
every oriface for blockage.  Back on went the carbs to no avail.  I took the 
main ground strap off and cleaned it up--no change.   I then increased the 
points gap to .020" and the problem partially cleared up.  Well, as it turns 
out the bushings in the distributor were shot.  I am waiting for the return 
of my fettled dizzy and am hoping that the problem will have been solved.  I 
will advise all later this week of my findings.

I am running the gp2 cam, decked block, polished and ported and shaved head, 
dizzy rebuilt by jeff.  running 10.5 to 1 or so.

no pinging,pre-ignition, or any other problems.

I used the GP-2 cam in our TR-6 when the previous cam lost a couple of
lobes. I had the head milled to bump compression up to approximately 8.8 or
8.75:1. No indication of any pre-ignition but I generally do use 93 octane
fuel.

Hello Andrew,

Thanks for the reply.

Do you have any idea if the 123 distributor can be used as a trigger for an MSD 6A series CDI ignition?

Thanks, Tom

Andrew, thanks for the contact!

RE: " why would you want to do that?"

1. Multiple sparks at lower RPM
2. Adjustable rev limit function inherent in the 6AL controller
3. The damn thing is already wired up and bolted to my inner fender

Thanks again for the info, Tom

Hi, Tom:

I wouldn't have a clue, so I called my cousin, Darryl Uprichard, who owns
Racetorations in the UK.  His question is why would you want to do that?
The 123 system is a full-integrated system and they also have a mappable
system.

If you have any additional questions, his email is
darryl at racetorations.co.uk and his phone is (011 44) 1427-616565.

Tom---Looks like you rounded up all of 'the usual suspects' for the cause of excessive pinging. One thing you didn't mention I will suggest -- that being the real possibility that whoever shaved the head did not break the corners after doing so. Unfortunately, unless you can get confirmation that this was done, you'll have to pull the head to check this. Sharpness at the edges of the combustion chambers and the sparkplug holes can get super hot if not stoned or polished down. 

IF---your timing marks on the damper pulley have shifted due to a breakdown in the rubber, you can get a feel for its accuracy, by noting where the pointer is when the key on the crankshaft is at TDC. Should be at "0". There is a more precise method for checking this, that being a tool for finding TDC without engine dismantling.  All that's required is removal of #1 sparkplug and inserting this (extended) plug. More info on this if you wish.

Dick

1.      Cranking compression. The engine was built to 9.5:1 specs,
45.6cc/chamber. My cranking compression hot is 195 +/-5 psi with a Goodparts
GP-2 cam, which strikes me as 10-15 psi high. Anyone else have a comparison
of nominal CR vs. compression with a similar cam?

2.      Timing. Jeff at Advanced Distributors does great work, but he
refuses to tell me what specs he built my distributor to, which is not
helpful. Does anyone have experience with the 123 Distributor, which allows
the timing curve to be manipulated? Is that distributor compatible with the
MSD 6 series ignition?

 

Thanks for your help. If I hadn't used forged pistons, I'm sure I'd have
blown a ring land by now.

 

Cheers, Tom

You can actually modify an old spark plug as is suggested in the last
paragraph.  Its pretty easy.  I have made such many years ago to establish
TDC.  Works beautifully when you are not sure.  However there is one other
issue: if by some chance the timing chain wheel and its mate on the crank was
not precisely set, it is easy for the timing to be off by a few degrees.

Tom---Looks like you rounded up all of 'the usual suspects' for the cause of
excessive pinging. One thing you didn't mention I will suggest -- that being
the real possibility that whoever shaved the head did not break the corners
after doing so. Unfortunately, unless you can get confirmation that this was
done, you'll have to pull the head to check this. Sharpness at the edges of
the combustion chambers and the sparkplug holes can get super hot if not
stoned or polished down.

IF---your timing marks on the damper pulley have shifted due to a breakdown in
the rubber, you can get a feel for its accuracy, by noting where the pointer
is when the key on the crankshaft is at TDC. Should be at "0". There is a more
precise method for checking this, that being a tool for finding TDC without
engine dismantling.  All that's required is removal of #1 sparkplug and
inserting this (extended) plug. More info on this if you wish.

I will second Dick's comments as I had the same problem after shaving and
raising compression to 10.1:1. Removing the head and having the sharp edges
carefully rounded off cured the pinging AND run-on problem.

All my best,

Brian

Subject: [6pack] Walter Mitty - Kastner Cup race T.shirt
Message-ID: <4F89CF37.90701@bright.net>

Hello lists. Triumph is the featured marque at the upcoming Walter Mitty 
vintage races at Road Atlanta. This event is also featuring a special 
all Triumph race and the Grand Marshall is "Kas"Kastner. Kas was the 
founder and head of the US Triumph Competition Department.  He wrote the 
Compettion Preparation manuals that served as the bible for generations 
of Triumph racers.   "FOT", group of TR racers, slong with Kas started 
the Kastner Cup award 10 years ago. Awarded by Kas and to his own 
personal criteria, this is a prestigious honor for any TR racer.
We did a production run Kastner Cup T.shirts for the FOT group. The 
repsonse has been excellent and another, small run of shirts is being 
considered.  Some of the proceeds go to FOT to fund things like helping 
with travel expense for honored guests, promoting FOT event involvement 
and more.

  So, if there is enough interest, we will do an additional print run of 
shirts. This is a one time only print run.  Due to the number we printed 
on the first run, we were able to keep the cost down. Shirt prices will 
be higher than previous run due to lower volume and set-up expense. We 
need a minimum 36 piece order to do another run.  Prices will be $15 
Small - X-Large; $17 for XXL.  If we have eough orders to run 48 or 
more, price goes down by $1 per shirt.  Pictures of  shirt are attached. 
If the images ares stripped, plesae email me and we will send directly 
to you.

There is a possibility that we could have them done in time for pick at 
Road Atlanta.  A go/no go date for ordering is close of business this 
coming Wednesday, April 18.
Please call or email with your order. All contact information is on the 
signature line of this email.
Thanks for your time and support. Ted

Subject: [6pack] Bucking--Jerking TR-6
Message-ID: <1A1ABCF958A14C44B4872B19C38BC805@office>

Well, so many have said that most carburetor problems are electrical and,  the
opposite, that most electrical problems are due to carburetors. So, may '75
TR-6 developed a serious bucking and jerking problem to the point where it was
undrivable.  I hope what I am about say helps someone down the line.

I replaced the plugs and the plug leads.  No improvement.  I then replaced the
points, the condensor, the dizzy cap, the dizzy ground lead, the low tension
block from the dizzy to the coil, cleaned the fly weights and checked the
springs on the retard unit--all to no avail.  I replaced the fuel pump and the
fuel filter.  I removed, cleaned and replaced the primary ground strap from
the battery to the engine block.  No joy.  I then took both Zenith carbs
apart, cleaned them, checked the float levels, put heavier oil in the dash
pots and put them back on the car.  No improvement.  Double checked the
condition of the battery when charging--no problem there.

It wasn't until I took the dizzy out again and measured the wear on the dizzy
shaft that it came to me that the wobble in the dizzy shaft might be the
source of the problem---and the reason the timing would jump 20 degrees when
idling.  I turned the shaft until the cam opened the points and pushed on the
rotor in the opposite direction.  I could close the point gap by doing so.

So,  I had new bushes made up and installed in the dizzy eliminating all
wobble.  Problem solved.  Now, the engine sits and idles smoothly, starts
immediately on the key, and seems to have more power.  I also removed all the
smog equipment and eliminated the vaccuum lines capping off the carbs and
other vaccuum-related openings.  I set the timing at 12 degrees BTDC at 800
rpm--and could not be more pleased with the results.  No stumble, no jerking,
no hesitation, and no stumble at low rpm while accelerating.

Thanks to all those  that made suggestions as to the nature of the problem.

Message-ID: <000e01cd201c$59549160$0bfdb420$@earthlink.net>

Hello,

 

Dick Taylor was very kind and sent me a piston stop that attaches in the #1
spark plug hole. My pulley was rebuilt by "Damper Dudes" and I never
verified the marks during the rebuild.

 

The tool arrested my piston at an indicated 16 degrees BTDC and 12 ATDC, so
it appears that my timing marks are off by 2 degrees. Unfortunately, this
doesn't solve my problem, because true TDC is at an indicated 2 BTDC, so
I've actually been running LESS advance than I thought.

 

No easy answers with these cars. 

 

Cheers, Tom

Message-ID: <3B4A7248-32DF-47FF-9917-D9322431DB0A@comcast.net>

The idle on my 6 has been a bit high (10-12k) since installing Joe  
Alexander's velocity stacks (the engine likes more air at Denver's  
altitude) but when I tried to cut the idle back I realized the spring  
on the idle screws (ZS 175s) had become compressed and I couldn't let  
the screw out enough to lower the idle speed without losing the  
tension that holds it in place.

So I removed the screw and spring and stretched the spring just a bit  
(from 0.376 to 0.418 in.) and was able to get the idle to come closer  
to the 850-900 range once I could let the screw out and could still  
keep enough tension so it wouldn't rattle loose.

You'd think changing idle speed would be a simple thing but you learn  
something new everyday with these cars.

Thank goodness for rev limiters.

Guess I got carried away and used the wrong dimensions.  More like  
1000-1200 RPMs.  It helped synching them again which I'd neglected to  
do for awhile and the idle was happier.

We all knew what you meant, it was just fun to tease.  A TR6 motor at 
12,000 rpm?
Probably not.  But at the Asheville VTR meet J K Jackson's race car came 
down the
hill sounding like it was turning at least 9 grand - wow!

List,

I'm replacing the rear springs on my 74 1/2 TR6.  When I took them out
I noticed they had the aluminum spacers installed.  Should I assume
that I need them for the camber to be correct, or should I not install
them and see what the camber is like?  From what I read I couldn't
tell if it was stock or not and wondering if a previous owner
installed them to correct camber from sagging springs.

John---These aluminum spacers were sold once sold by Triumph dealerships to customers who reported too much negative camber on their IRS cars. New springs most likely will take care of this. Install the new springs, and if they are as originals, the camber should be correct. Several options if the camber is not to your liking ... try the spacers, or do a mix and match with the trailing arm brackets. Or invest in the Goodparts adjustable brackets.

Subject: [6pack] Rear spring spacer

List,

I'm replacing the rear springs on my 74 1/2 TR6.  When I took them out
I noticed they had the aluminum spacers installed.  Should I assume
that I need them for the camber to be correct, or should I not install
them and see what the camber is like?  From what I read I couldn't
tell if it was stock or not and wondering if a previous owner
installed them to correct camber from sagging springs.

John V.
