Having some issues with a rebuilt quadrajet I purchased from Holey. Backround - 82 K20 M code heavy emission hot air choke 350 465 everything is hooked up correctly and nothing is missing under the hood. I just put a crate motor in and made sure everything was installed back to stock so I can pass emissions. Here is the problem I am having - The choke just does not seem to opperate correctly. It always wants to go to fast idle even if the motor is at opperating temperature. If I play with the throttle I can get the fast idle cam to fall into the correct position but it just does not want to stay there. It looks as though gravity is suppose to drop the fast idle cam when the choke coil expands but the linkage is pretty ballanced so there is nothing forcing it down... I am assuming the spring tension of the choke coil is suppose to force the choke closed when cold. That is how I have it set up. That works just fine but when it heats up, nothing is forcing it open. The coil just backs off and gravity is suppose to make it open????? If I am wrong and the coil is suppose to force it open when hot (which I prefer) then there is nothing to close it when cold. nothing at all since the fast idle cam and butterfly valve would have to fight gravity all on their own to close up???? So I doubt that is correct... Either way, how the hell is this hot air choke and fast idle cam suppose to work and how does one set it up? I have a book and the carb came with manuals and I even have directions from a rebuild kit but none of them reall explain how this thing works. If I set it up like I think the books tell me to, there is nothing to controll the opening of the choke other than gravity so I must be doing something wrong Tips, advise, tech article, hand holding , any help will be appreciated.
