pretty sure this is it but just picked up a 350 4×4 and gas tank full of rust. replaced tank and cleaned out carb but wouldnt start. the pic shows what i did with the little black plunger that goes inside the bowl of the carb.
also, since ive never heard this bike run is there a standard # of turns out you would turn out the air mixture screw? (i believe its called that) it was turned out 2.5 turns from bottoming out.
thanks
