Wow... Thank you all for all your comments and recommendations. Just
to make things clear... It's a Briggs engine and yes, it was I who hit
a stump and bent the crankshaft. I new it was bent and Sears confirmed
it with a $220 quote for repair. Instead of having Sears do the
repair, I ordered a new shaft which cost me $75 including shipping and
I'll attempt the repair myself.
Right now, I'm having a tough time getting the flywheel off. I'll try
to get it off with hammering a piece of wood against it... although, I
think I should find a repair manual somewhere for this Briggs
engine... cause after the flywheel comes off, it looks like the lower
pan needs to come off. It's looks challenging but should be time well
spent tinkering in the garage.
Thanks again for all your help and direction.
