Re: 89 johnson j225txced wont start just backfires
Timing is way off. Usually caused by a sheared flywheel key, which is normally the result of of flywheel being put back w/o being torqued. Crankshaft taper must be clean and dry (no oil) and the flywheel nut must be torqued, or the key will continue to shear until the flywheel and/or the crankshaft are destroyed.
