    quadrajet on an 82 350. i've had trouble trying to adjust the idle screws because i can't seem to find a tool that will fit them properly. the heads of the screws are flat on two sides and rounded on the other two. is there a tool made specifically for these? i can imagine something like a really big version of a valve core puller.

    You're supposed to get a certain size of metal tubing ( can't remember which one) and pinch the end of it down till it fits. It just takes a short piece, then you can throw it in your glove box.

    Snap on makes one. I forgot the part number. They were the ones that Jet Performance gave me for the quadrajet I bought from them.

    Go to a parts store and ask for a carb adjustment tool. For about $7 it is a screwdriver with a spings shaft and holds for bits in the handle to work on different styles. It will have the one you need and is very easy to use because the shaft is flexible.

    I bought one of those and it did not have the correct bit. You can use tubing and bend one side flat as said before. I'll check on snap-on's site for the tool #

    I got one of those kits from Autozone. It came with several tips to fit different apps.
    Check out the Lisle kit at the end of this page

    That's the one I used and worked fine. :)

    I believe the snap-on part # is S6139. You can call Jet Performance to verify that is the one they use.

    i got 82 with 350, mine had the quadrajet when i bought it, but i have since replaced it, one thing to check is at first my adjustments were blocked off, so i had to remove the plugs, second i got a carb adjustment tool from napa, for about 10 bucks..

    thanks for all the responses. i'll check on that tool to see if it has the right bit. if not, i have some old hvac copper tube left that i could try. those screws sure are hard to get to, especially on the passender side. a carb spacer would probably be a nice touch for making adjustment easier.
