    I'm gonna to rebuild my first Q-jet, but I can't find the right carb kit part number for my carb. I've a Q-jet mfg. by Carter numbered 17059206. Could someone help my out with this. Maybe one of you have this number wrote down somewhere in his garage. I live in Italy, so I can't just go to the first auto parts store and ask them.
    Any post will help.
    Thanks

    Luca

    Hey Italy - My wife and I went to Italy last year. We flew into Milan then spent a few days relaxing in Lake Sermione (Spelling?) and then went to Venice and Florence. Spent a little time in Tuscany too. Loved it a lot. Anyway, it is probably hard to find American car parts in Italy. Come to think of it, while we up at Lake Sermione, I saw a Blazer but it was the only one I saw the whole time we were in Italy. If you want, I will track down the rebuild kit here and send it to you. It is probably easy for me to find something like that. Let me know if you want my help.

    Check out this page to ID the carb: http://www.edelbrock.com page to see which part number is the rebuild kit for their equivalent Q-jet. Then order the kit from http://www.carparts.com should have a rebuild kit, but you'll need to be sure about the carb model.

    The problem is that every single year just about, the air horn changed, which mandated a different air horn gasket. External ID will tell you the general vintage, but the only way to (hopefully) get the right kit is to use the casting numbers. For example, I have a '77 and '78 Qjet (his should be a '79) and the 77 and 78 air horns are different, as well as the gaskets.

    I didn't know that. I thought all 4MVs where the same and all M4MCs where the same.

    Me either up until I broke the '77's air horn and found a '78 to replace it with. It would bolt up no problem, but the passageways were different enough that I could easily tell it wouldn't work. Externally, the only difference was one fitting which was for air from the air cleaner.

    On top of those differences, it appears that very often GM changed the size of the idle mix bleeds, making them tougher and tougher as the years went on, to make them idle well with a "lopy" cam. As well, the secondary air valve tang (stops the valve from opening all the way) was generally increased in size every year, more and more limiting the Q-jet to even less WOT capability. Both are easily changed to "pre emissions settings"
