| Stop using starter fluid in a mower. If it doesn't start with a tsp of fuel dropped into the carb, it needs repaired. 
 It sounds like you have a sheared or partially sheared flywheel key. Remove the recoil starter, then the flywheel. The key it what "clocks" or "times" the flywheel to the crankshaft.
 
 A new mower should last 5+ years if properly taken care of.
