Title: Choke assembly comes out
Post by: dlphil10 on July 27, 2019, 11:25:19 AM
When I was adjusting my choke the main shaft that interacts with the fast idle cam, choke pull off linkage, and choke lever popped out of the main casting. I got it back together but it's very loose. Am I missing a piece or is there something that I can do to secure it better?

Sure, the carb is 7029262. The shaft the fast idle and pull off cam are operated off of that goes into the main body is what can pull out. Picture attached.

Difficult to see anything from the pic. 

If the shaft came out of the bracket you'll need to remove it and drive it back in place and stake it to keep it from coming out again.....Cliff

When you say loose, how loose, you should be able to move cam up and down easily, You don,t have cam on backwards do you??? Just asking. seen it happen. There is play in the lever that choke arm go,s thru & the outside screw should hold everything else tight. I usually ad a small drop of red loctite to the screw.

Mr pontiac are you referring to the tang that sets how far off the choke pull off opens when the engine is running? If anything, it needs to be opened more as it seems rich when cold.

Cliff where do you stake the part the goes into the carb and operates the choke lever? On the outside of the carb where it meets the main casting? This is getting worse as it will pop out going down the road which will cause the carb to inconsistently hesitate briefly as the choke flaps around.

The center housing and shaft MUST be part of the bracket, so staking and some Loctite may be needed to keep it in place.  You may find it necessary to "peen" the bracket so it presses in place......
