just replaced my CB and the thing runs way better when cold now. i didn't have to remove the auto choke, either.

i covered the carb up with a rag and then used a die grinder to grind down the ends of the rivets that attached the CB to the auto choke-to-CB bracket.

Image

then i tapped a small screwdriver in between the CB and the bracket to separate them.

Image

then i pulled the CB out of the bracket.

i found that after removing the tiny clip, the choke linkage to the CB could just be removed from the CB arm. i removed a good CB from my spare bad carb using the same technique as above, then i put a dab of JB weld on the mating faces of the attaching brackets. the remains of the rivets positioned the CB appropriately and the JB secured it. i carefully attached the linkages and now it actually runs properly when cold. i never realized how crucial the CB was to cold running, now i know.

Great job!

I certainly did notice those rivets. I am glad you were able to remove it easily without removing the automatic-choke coil housing. Certainly with the choke not functioning properly, the engine will run poorly because of the messed up air - fuel mixture. A fully open choke with a cold engine (which may be caused by a bad TVSV) will stall it just as a fully closed choke (which may be caused by a bad choke breaker).

I did notice how much corrosion you have in your engine parts. Mine look brand-new in comparison to yours. Living in Southern California, now, I appreciate how much difference climate makes in your engine. :)

yeah, and this whole car is particularly ugly. i rescued it from a hippie who had neglected every single possible aspect so it's been a much bigger, longer, more involved project than i had anticipated. i would never have guessed though because the thing drove to my house just fine! that's the beauty of these cars. tough to kill.

I know -- these cars run well even if they've been neglected. Mine was only 10-year-old when I got it from a student, who had got it from another student. It was neglected and every time he took it to a cheap mechanic in Chinatown, the mechanic tampered with something (like another emissions part) and messed it up. In the 17 years I had the car, I think I've finally rolled back all the tamperings and it now runs almost as good as new! The icy looking paint is the only cosmetic problem.
