Re: Flywheel Key keeps shearing !
Should have since it been over an year since the last post.
BTW this only applies to 280000, 310000, and 330000 prior to 07-01-2012 (date code 120701****). Briggs redesigned the flywheel and crankshaft and are using double length aluminum key on the new engines. Don't use the steel key on the newer engines.
