Okay so I got the thing moving. I believe it's what's called a freewheel clutch. I sprayed the small gap between the bearing and the sprocket with Dub D 40 and let it sit overnight then shot some compressed air through there. Viola! Spins freely backwards but catches when rotated forward. I reinstalled onto the scooter, started her up and putted around the yard. The engine was blowing white smoke out of every orophus it has after 3 minute ride. Scratchin my head once again!
