suze400 replied to kunkle's topic in CRF 150/230 F/Lthanks, your post made an important general point! it turned out i had a carbie issue but was chasing my tail over it. now that i put a known good carbie on the motor runs fine. it is off an old xl, i ll have to get a 30mm or 32 mm mikuni i think :-) in the process i checked the valves which were a bit tight. made sure piston was on TDC by taking out the plug. that way the timing mark is of no concern, at least for the valves.
