Hi everyone, and for those in the position - Happy upcoming Fathers day :-)
My pretty red TR3 has still not recovered from her misfiring disease. As you
may remember from my last post a few months ago I had to get towed home for
the 3rd time because the car was misfiring and eventually misfired itself to
death.
I did the following which appeared to help, but really did not:
1) Adjusted the valves which was necessary
2) Replaced the spark plugs with Champion
3) Put back on the distributer cap and wires that came with the car
4) Replaced umpteen rotors
5) Removed the Pertronix electric points and put in new points and condensor
6) Timed the engine statically
The only "to-do" from that was to replace the regular wires inside the Dizzy
with the super fine ones. I have ordered these from Moss.
The current symptoms are worse and more agressive than before - I can't go
anywhere now. The car will start fine and run fine when we first start off.
After about few hundred yards to a mile or so it is OK then out of NOWHERE
it feels like it drops a couple of cylinders. Tonight it was so bad it kept
crapping out and would idle but when I applied gas it would accelerate on a
few cylinders then suddenly die back to idle. Then it finally crapped out.
Fortunatly I was close to home. The condition goes from OK to
sputtering/missing to really bad sputtering/missing to dire missingto dead.
Here's what I have done so far, in addition to the above:
1) Used a Colortune to examine the combustion color - the front 2 cylinders
are running Blue which is great, and the back 2 are yellow which is rich.
Lifting the pin on the carb about 1/4 inch causes and increase in RPM for
both carbs.
2) Used a Syncronometer to measure airflow through the carbs at idle - it is
almost exact through both
3) Plugs are tan-light tan in color when she is run. After an idle and no
run they are black and sooty.
I don't know if the problem is heat related or distance related. The car
has always started fine with no choke. As an aside - I got my BMHT
certificate today - it used to be Primrose Yellow with Red Leather seats.
Now it Signal Red with Tan seats ;-)
If you can help me I would REALLY appreciate it. I'm willing to try most
anything at this point as each Summer day rolls by. Help me fix it so I
don't succumb to the V8 implant disease!
