I'm the first to admit that I have NEVER in my life seen this leather bit on
the fast run cam. I'll also admit that HD8 SU's don't have a fast run cam.
The choke cable acts directly on the jet/diaphragm mixture thingy. Most of
the Healeys do have leather bushes on the throttle linkage however. So I'm
not sure what you saw.
When pulling the choke cable one should also depress the throttle pedal so
there is no frictional resistance from the cam, if fitted (mostly other
marques). Also every 20 years or less (grin) one should lubricate the cable
for Pete's sake if nothing else. If the dash is coming out with the cable
then it's probably past time to lube the cable or fix what ever is binding.
Note: early cars did have the fast run cam on H4 types and the HS6's had a
weird non adjustable lift bracket of sorts that was not adjustable except
for the amount the linkage could pull the jet down.
Pretty sure we aren't on the same page.
Don't be put off... I called my physicians office at 9am today and was told
he'd call back by lunch. I called back at one and was told he had the
message on his desk... no call back. I'm pissed that they take our money or
the insurance co's but, can't answer a single question when the cell phone
is in their smock's pocket... vent, rant curse... OK I'm better now..

Subject: [Healeys] Cam shoe rod sticking
Bob Johnson, Steve Byers and David Porter:
Last Saturday, 19 Nov., the Tampa Bay Austin Healey Club had a Tech Session
at Paul Tsikuiss shop, Tsikuiss Classics, Lakeland Florida. Paul is a
charter member of our club and has been restoring cars for 31 years.
Our tech session was about carburetors.
Paul asked the BJ8 owners if they had to place one hand on the dash before
pulling the choke cable, and if we had return springs installed. Of course
we all answered that we did. He showed us why that is.
There is a leather piece that the cam sits on and when it is new it rotates,
but after years of heat and cold, water and oil and whatever, it becomes
hard and the cam cannot rotate on it, so consequently the choke lever does
not return to it resting place without the help of a spring. What Paul did
to correct that problem was to: 1. Remove the brass cam shaft and polish it
2. Remove the leather piece and install a piece of brass tubing, he used an
old throttle shaft cut to fit the opening and secured it with a nail, head
on one side and peened on the other. If you dont have a throttle shaft I
believe he said a 5/16 brass tube cut to size would work. Each of us got to
hold the carb he had set up and it worked perfectly, no springs will be
needed. Also, when he reinserted the cam shaft he lubricated it with
Dri-Slide. This is graphite in a liquid that once applied, the liquid
evaporates and the graphite stays, and no dirt will stick to it. This
Dri-Slide can be bought at gun shops. I hope I explained it well enough
because I am going to do it myself and I plan to do mine in the near future.
Also, Paul showed us Nash Healey #1 that he had just finished restoring and
it was magnificent.
