manual choke?

<< < (2/2)

Rickard080TA:
I have a manual choke on a 1980 Pontiac Trans Am. I have not be able to find information on how it works. I have learned alot about the electric, but not manual. I am far from being a mechanic but here is my situation. Car is hard to start, once it is warmed up it is fine. The manual cable moves about 1/4 of an inch so I know its stuck somewhere. The part that opens and closes to allow air is always open. If you look at the pic it is open right now. Thats a cold engine. My questions are..

1) Is there a difference in the linkage between electric and manual once you get past the choke itself?
2) I am unable to find a good site that shows conversion from manual to electric, even in this forum, anyone know of one?
3) I have rivets not screws holding the choke on, if I break the rivets off, are there threads so I can screw it back on?

what you have is a piece of cake to convert . you have a hot air choke that someone has made manual. easy fix . spend 50.00 or so and get an electric choke kit from cliff . drill the rivets out throw away the gasket and plug the little hole behind the choke assemble . install your electric unit adjust and drive. do not use to big of bit when you drill the rivets. i prefer to just drill the heads and drive the rivet out .the kit comes with self tapping screws. i like to tap the housing myself.you need to find a power source with the key on.hth.

Thanks for the reply. Any suggestion for what I would use as the power?

 Welcome to CHP!

 Any 12v source should suffice. Somewhere even on the fuse block, that gets 12v key on. :D
