if it backfires it could be timing or else you have it flooded from trying to start it. You didn't say if the engine is carb or fuel injected. If it is carbed, let it sit for awhile to let the gas drain out of the carb. If it is fuel injected then it is probably timing. year make and model of vehic and millage
