    My '86 K5 w/ 305ci has a 4bbl Quadrajet carb that is acting up. it doesn't idle right, and the electric choke is about shot on it. the truck has ~206,000 miles on it, and instead of messin with this carb more so than i already have, i just want to replace it.

    I've looked on ebay for Quadrajet carbs, can anyone tell me the model number i'll need for my truck? i'm pretty sure it's a 750cfm, just need someone to verify. i'd greatly appreciate any info you guys can give me!

    You need to get the part number off the carb that you have. It will be a 8 digit number. Mine was 17085508.
    It's on the driver side of the carb, etched in the body of the carb.

    Impressive /forums/images/graemlins/thumb.gif Have you looked at the jegs and summit rebuilt quadrajets? There not TO expensive, also I belive a quadrajet rebuild kit is pretty cheap /forums/images/graemlins/thumb.gif

    Be careful though......certain carbs have sensors on them (mixture, TPS, etc.) These are required for emissions reasons in California, and the aftermarket carbs like the Edelbrock and Jet models do not have them. If you don't have to worry about emissions though, GO FOR IT!
