    Ok Winter is coming and I still need to either get a new carb or rebuild mine. I have the stock carb for my 85 Jimmy with a 305. Should I rebuild it or buy a brand new aftermarket carb for it Id like it o be reliable for the long winter ahead.

    I went through 3 remanufactured carbs before I could get my Blazer to start fine in cold mornings (and I live in warm weather). It's an Edelbrock Q-jet #1902. I highly recommend it. Edelbrock has an application for different years if you need to stay legal.

    Rebuilding your carb will fix problems with old gaskets or bad adjustments, but deeper problems like bad vacuum canisters and worn shafts will remain there, giving you more headaches.

    I have an Edelbrocke 600cfm carb w/electronic choke. I'm not sure if it's the quadrajet version, but I love it. My 1977 chevy truck always will start on the first crank or two even when it's minus 60 outside. I have two springs on the carburator though so that it idles down easier.

    I'm rebuilding one of my Q-Jets right now, I'm hoping that I will have good news when finished. The Q-Jet is a good carb for off-roading, but if the rebuild doesn't cure my ills I'm going Holley.

    Not going to get a better all around carb than a Quadrajet. Rebuild it correctly and you can't go wrong. If you are worried about it, have a carb shop check the drivers side of the primary shaft for slop, and have them bush it if necessary.

    If you have the bucks I think you should get the aftermarket Q-jet carb from Edelbrock. Or a remanufactured one from JET<a target="_blank" href=http://www.jetchip.com/fuel/streetmaster800.cfm>http://www.jetchip.com/fuel/streetmaster800.cfm</a>
    They are both good carbs and its nice to have all new parts for reliability and the throttle shafts are rebushed..

    If the carb has not been sitting during it's life, almost no parts (that a "rebuild" kit won't replace) "wear out". The float is something I would likely replace, but everything else the rebuild kit would fix. Primary throttle shaft wear and corrosion from sitting are the Q-jets worst enemies. If it hasn't been sitting, corrosion can be pretty much ruled out.

    go for the Q-jet Edelbrock 1900s series. just put one on my 72, adjusted the idle screw and drove off. My last one(original) was rebuilt(by me, not an expert) like 2 times and could not get the darn thing working correctly. I figure it that one lasted 30yrs a new one should last as long.
