I have a Sears Craftsman lawn tractor with a 19.5 HP Briggs & Stratton engine. The plastic toothed wheel on the starter that engages the flywheel is completely stripped. I have a repair kit but am having trouble removing the starter. Can I safely remove the flywheel instead. I can see that if I lift off the flywheel I can replace all of the parts at the top of the starter but I'm worried that I won't be able to get the flywheel back in place.
