You may have an intake valve staying open or the spark timing may be off from a slipped flywheel and key. Can spray liguid wrench in the intake to coat valve stem . You would have to take off the flywheel hold down nut and pull starter engage ring to see if the groove in the flywheel matches the groove in the crankshaft. Ive had blowers, weed eaters, tillers and all kinds of small engines break a flywheel key for no apparent reason. Sometimes they are just a little loose and wear out or snap.
