I have removed a "Kinroad" engine and gearbox (2 speed forward with reverse). It's just taking up space in the garage. The stator got jacked up (I think) when the nut came loose and bounced around in there. The engine promptly shut off. I had to replace the woodruff key. It started briefly.....then I gave up and pulled it off the cart. I went old school........heavily modified Tecumseh and a TAV-2 system. Anyone interested??
