    How do I get to the center carb screw?

    Hi all. Randy just rebuilt my carbs. Have started it a few times in the garage and can tell already it is very rich both by the amount of mosquitos on my garage floor and viewing the piston heads through the spark plug hole.

    Anyhow, I can easily get to the Mag low screw and the PTO screw is a little tougher, but that center screw looks almost impossible to me. I know that I'll have to remove the oil line, but then what???

    I did see an old post from Al with a bunch of tools and one of them was a carb adjust tool, but thought it looked too big to even work on the center low screw.

    Thanks in advance all!

    If you have a thin and longer than normal screw driver, you can get at the screw by coming at it from the front of the carbs and slip it behind the accel pump. You will have to come at it in a little bit of a downward angle but you should be able to still turn the screw pretty easily. You shouldn't have to remove any oil lines. Also, the tool Al discusses is not for use on Keihin carbs it's for a different brand.

    Save yourself a huge headache on the Keihin carbs and use the adjusters with the T handles, moocho easy.
    They actually make the T handle adjusters for the Keihin and Mikuni carbs.

    From Watcon's site

    $60 bucks per set? Is that per carb?

    I have a bunch of them, post a picture with your stock unit on top of a ruler so I can see if what I have will fit your carbs.
    You might want to count your turns from bottom to see where you currently sit.

    I assume this means pulling the entire screw out. If so, I cannot imagine getting this screw out without some major disassembly of the carbs from the rails. Am I missing something? There must be an easier way of doing this.

    JetskiMN, I tried the longer that usual screwdriver but that didn't work. I thought that maybe one of those long coffee stirrers would work, but that didn't even come close!

    I am sure I am missing something...please help.

    BTW, does anybody have one of these? Looks like it may just work, but I'd buy the new screws from Watcom before buying this.

    Just in case someone else searches, the center carb screw can easily be turned using a 4 piece pic set. Actually just the hook tool works perfect. I am able to catch part of the knurled patterned on the screw with the sharp hook and it moves very easily. A long 10" pic set would work perfect but I used my snapon mini pic set.

    I think Randy's trick with the hanger is pretty trick. Just get a standard metal hanger, cut out the straight section and hammer one end flat enough to fit the screw. Bend the other end in a 90 and you have a reference for 1/2, quarter turns etc.
