Hey guys I couldnt find a new flywheel anywhere so I made a mandrel for this one and tested it (safely) at 30,000 rpm for a few minutes in a router and it held together so I figured it would be fine.
I got the engine running and its working great. Its modified but it really rips for a trimmer engine. Heres a link to a video of it in my boat:
