the pull start is broken so its off. ive been trying to start it with a cordless drill. when i rotate the flywheel, i can feel it get tighter at the top but it doesnt seem as tight as it used to be. the flywheel seems to turn really easy.
im unsure as to what you mean about "how much fuel has it had.'' if you mean has the engine been broken in, yes it has. and it has had many tanks ran through after that. if you mean how much is it getting now, i got gas in the line to the carb and i primed it a few times.
if the engine is shot, what is a good replacement? just go with the same one? rebuild the current with new parts? i read once that O.S. engines fit this truck. dont know which one or if that was even true.
