i need help. i have a 1974 kawasaki 250 f11. and i cant get it to run. it seems to me that there is something wrong with the timing. but that dont make sense because it is a single cylinder so the timing is really simple and seems to be like an unlikely reason. so have any of you ever had this kind of trouble.oh yeah and yes i put gas in it and yes i have good spark. it also seems to be getting fuel to the sparkplug but just wont try to run it only sputters. i would really appreciate the help. thanx.
