I am new to this forum and look forward to enjoying it alot. I do have a question to begin with. I am currently working on a friends craftsman mower, that he has hit somthing very hard with. In the past he had the flywheel key replaced. After dis-assembly, I found that the key was intact but mis-shaped abit. I installed a New key but it still acts like it is out of time. Is it possible that he might have spun the cam or other internal parts.

Welcome to MLMF, antlerdancer!

After you replaced the shear key...did it run, or try and run? Does it backfire through the carburetor?

If you have a dial indicator you might try and see if the flywheel has run-out. You can do this with a cordless (or corded) hand drill and socket to fit the flywheel bolt. If the dial indicator has more that .015"-.020"- then Austen may be correct and your friend might have bent the crankshaft enough to permanently disturb the timing...

I think you're right about too much play. I'm thinking, other than remove and replace the flywheel and guessing the best spot, you might be much better off finding a good replacement flywheel.

The flywheel is on a I.D. taper, right?
