yes i have made ajustmants to the carb needle but with no luck. when the engine takes about 3 seconds to reach full RPM does this mean i wind it out for more fuel?
when it runs at very low RPM even though given full RPM, does this mean it still needs more fuel?
sometimes it would rev then slow down then rev then slow down fairly fast?.
another question, do i set the main needle valve first, then the low needle?
hope i explained it ok
