    the fuel screw is located right on the bottom of your carb, it will be hanging down. turn it to the right in small increments until you get the desired fuel flow.

    Here's the fiche of your carb. I've circled the fuel mixture screw in red. you may have already read on here, dialing in the fuel screw is usually no more than 3/4 turn delta. often it's less than 1/2 a turn in one direction or the other. it's sensitive so more in this case isn't better. if you can warm up your motor...let it idle and turn it one direction and the idle gets rough, note the position and then go the other direction until the idle gets rough, then split the difference and she should be pretty well dialed in.

    keep in mind the fuel screw is for pilot jet mixture issues...it won't fix main jet issues...for those you have to get the right main jet.

    good luck.
