:think: ok so , i got an old rm 250 to fix up for 200$ only needed a chain and it went. i drove it for 2 hours, and it stalled and i didn't have a kickstarter on it and knowone around to push me , so i parked it. A friend of mine,,( he is experriance with assembly and dissasembly) took it apart( the carb off, pipe off, and put a new head gasket on it and gave it a paint job . he put it all back together and it wouldn't start. funny thing is , it has spark 150 pounds of compression and its getting gas from the carb. i put gas right into the cylinder and it still wouldn't even fire. is there something stupid i missed or something/? anyone know anything i could try? :think:
