    I have a rebuilt q-jet with electric choke. My problem is that the choke is over choking. Runs fine once it warms up and the choke cuts off. Does anyone know how to adjust the electric choke so that it's not so rich. I'm not to familiar with carb tuning so the more details the better
    Thanks

    I do not now if there is a way to adjust it. But you can buy just the choke for $45.00 at napa auto parts. You need the carb # off of the right hand side......

    On the passenger side of the carb is the choke housing. It is either screwed or riveted to the carb. If it is 3 screws the adjust is easy, loosen the 3 screws and turn the housing to adjust. I adjust it when the engine is dead cold and not running. Turn the housing until the choke plate just starts to open, then back it off a litle bit and re-tighten the screws. If you have rivets instead of screws you'll have to drill out the rivets and re-rivet it after you've adjusted it.
