    Does anyone have a digital manual for 1990 Yamaha YFM250 moto 4? I will be rebuilding the carb. because it is hanging up.. still after several cleanings. When i give it throttle it stays at a high rev.. seems as if the carb needle is sticking and not allowing the slide to full sit on the idle screw. Has anyone ever has this problem.. hoping a carb rebuild will solve this issue. Looking for stock carb settings also. Thanks in advance.
