Since I've owned my GT6, about 2 years now, I never have been able to
get the carbs to behave quite rightly. The chief problem is that
they won't idle correctly -- even with the
throttle stops fully out (i.e. the butterflies fully closed), the
car still wants to idle high. And now that I've put in electronic ignition,
a header and free flow exhaust, the lowest idle I can achieve is about
1100 rpm, again, with the stops all the way out. As you can imagine,
with this setup, the air flow is not balanced, and yes, the butterfly
valves are installed correctly.
Having said all of that, I'm wondering if it's just time to send the carbs
off to Apple for rebuild. I believe they have about 70K on them; would
it be reasonable to expect that the jets have grooves worn in them,
causing this high idle? Also, can you SEE such grooves? (The throttle
shafts seem O.K., but I suppose these could be letting in air as well.)
In any case, before I spend $350 with Apple, I thought
I'd conjure up the list spirits for advice here. I'm also sort of
wondering if this isn't just the time to think about carbs other
than the stock 150's, but I do drive the car on the street, and I'm not
eager to encounter smog law hassles.
