How To Adjust the Choke on Rochester Carburetor
This video shows how to set the Automatic Choke on a Rochester Carburetor with a 350 (small block) chevy Engine,
Rochester Quadrajet, the results!
Two mishaps, the first shown here, the choke coil I got was wound backwards, it made the choke butterfly wind up TIGHTER as the engine warmed up. I swapped on the one from the old carburetor fast enough, the second mishap made me feel like a crud and what did I mess up later that evening. The car would not start leaving the Etobicoke -Queensway show. It was not getting gas. We got it running by priming the carburetor, and boy, was I ticked at myself. In the end it was not my fault it looks like. The new accelerator pump umbrella and rod was a very poor and frail design, the umbrella came detached and stayed at the bottom of the of the pump well, and was a distressed mess. The maker will get a note from me. The upshot? The old assembly went in, all is perfectly fine, the slight tip-in hesitation is gone now too. Stupid lack of pride it seems these days making parts for even simple things like an old carburetor.
