[Healeys] Carb Bush Removal - HD6 ?? Rock Steady Idle

[Dan Stromquist]

My BJ8 with HD8 carbs starts to idle faster and faster as it heats up.  It
goes from about 500 RPM to 1000?  Any ideas why?  Also, if I pump the gas
frequently it backfires.  My guess is I am just getting some unburnt vapors
into the exhaust system that ignite and this is probably normal.  Anyone
else have these problems and what was the fix?  I stopped pumping the pedal
but still get a little fart every now and then.
Dan

Tom -

Have you tried a PTFE bushing in there instead of bronze? HD8 carbs use PTFE
bushings and they really make a big difference - the shafts never wear and
it is easy for me to get a rock steady idle at all temps on my HD8s.

Was thinking this might be a better, longer lasting option.

I was thinking of just buying some of these, and then having them bored out
to 5/16" at a machine shop.
