Only thing done to it is the baffles r removed.

that can lean it out so you'll need to richen the pilot circuit up at least. also, don't let it idle for long on the stand. needs air flowing through the radiators to keep from overheating.

thanx guys I'll have to mess with it today ..would it be the fuel air screw on the carb?

by **crfsonly** » Tue Dec 27, 2011 12:31 pm

fuel screw is on the bottom of the carb (float bowl) area. in the photo below it's the brass screw (yours may be a different screw but in the same location)

Should I adjust it when runing

by **crfsonly** » Tue Dec 27, 2011 2:53 pm

setting the fuel screw mixture-

adjust the fuel screw when the motor is at full operating temperature. turning the fuel screw inwards until the idle slows or runs rough, then turn outwards 1 1/4 turns from this position. For example, if the idle slows or runs rough at 1/2 turn from closed, then set the fuel screw to 1 3/4 turns out (1/2 + 1 1/4 = 1 3/4).

hope this helps.
