pulled the carbs, i dont know much about carbs. there are two screws in there the one withe needle in it, and another small one. im sorry i dont know the names of them. but the carbs that dont work wont let any carb cleaner thru those small screws. the carbs that work spray right thru. so i will soak those overnight and see where im at tomorrow evening after work. could any one sirect me to a diagram of these carbs? im pretty sure the engine is a 74 and the carbs are keihin thanks
