Choke Question

<< < (2/3) > >>

Hikin Mike:
Couldn't modify my previous post.

Looks like the 34735 and 37623 are for a 1968-70 Pontiac. Makes sense now because the motor was out of a 70 Bonneville. I swapped the carb years ago.

Going to assume the fast-idle cam 40843 is for the 68-70 stuff?

Kenth:
You are correct on those choke parts.
Your carb is put together of at least 3 different carbs, 1971 Buick fuel bowl, 1968-70 Pontiac throttle plate (Made by Carter) and 1973-74 Buick air horn with a non-Buick choke blade axle and rod.

1965-69 Qjets uses a plastic fast idle cam, 1970 and later cam is metal.

I am posting pictures of a 1969 Pontiac 7029268 and a 1971 Buick 7045140 to compare.

Hikin Mike:
Thanks for the info, Kenth, that was a big help. When I said it was a Frankenstein carb, it really is. Didn't mean to do it, it just happened. I had that carb "gone through" about 30 years ago. Don't remember who, but it was before I heard about Cliff. Car sat for 11 years and I've been driving it the past 4 years now about 1000 miles a year. Just recently tried to connect a functional choke. Hence the questions.

I installed the 34735 (bracket), 40843 (Fast-idle Cam), and 37623 (Lever).

How do I adjust the choke?
