    I have been trying to figure out this carb. what does the little screw on the pass side do? and are the two screws in the front the mixture screws?how do you set it all up?
    Im going to pick up the Qjet book when I go to a book store that has it.

    Thanks Shawn

    that book should "splain" it all. A rebuild kit will have the instructions for setting each of those also. Pick 3 are the idle mixture screws.

    With the engine running , choke on , and someone inside looking at the tach who can yell at you , you adjust that for the proper engine speed on warmup . I just did mine by ear , and it was set at about 1600 rpm until my choke quit working recently ( like a year ago LOL , no choke needed in Phx area , running too good to touch it again ) .
