I take it that you know that the air/fuel screw is only for idle to 1/4 throttle? With a pipe you usually have to fidget with the main jet.

With that out of the way, the air/fuel screw is on the bottom of the carb. Its a tiny brass one.

it is a brass colored screw located on the very bottom of the carb. you will have to adjust it with a flat blade screwdriver. i would turn this screw out around a 1/4 of a turn. this will make the idle circuit a hair richer to accomodate the pipe.
