Inliners International Forums General Discussion Engines bad vibes

I haven't seen anyone start an engine with the flywheel off, but that doesn't mean it can't be done. Remember the starter spins the flywheel to start the engine.

I would visually inspect the flywheel and the dampner (my guess). If you have a dial indicator you could found out if the flywheel is warped. Make sure all your bolts are there for the flywheel. Make sure your dampner is held on good. Check your timing and make sure your mark on the dampner lines up where it's supposed. I.E. make sure the outer ring hasn't slipped. Just a few guesses. Good luck. John
