Timing issues?

[wan37]

I think I could of messed my engine up.I pull the magnet off and there's no wood-ruff key.I think it really messed my motor up but not for-sure.I would start it and it would idle good as it started warming up then the idle would rise with the temp then it would start knocking then I would shut down.So I hope it didn't ruin the motor.After I put the magnet and a new key back in.Is there any thing I should do before start up?

yeah, take the head off and look to see if you melted any of the top of the piston. Also look for the aluminum streaks that a partially seized piston leaves on the cylinder.
