ive had golf carts before but never a 2 stroke marathon. the guy i got it from rebuilt the topend because the oil pump locked up. no biggy, it runs great but i ran into a dillema today, it had a full tank of gas but i ran out today, anyone know the mix ratio for the oil and gas? also anyone know what spark plug goes in there? i dont think the correct one is in there. any help is appreciated, thanks.
