My Chinese 66cc engine is cutting out and bogging when my clutch is engaged, but it runs fine when I disengage the clutch and coast. Everything is stock. The chain does produce a lot of friction because the stock chain tensioner doesn't mount perfectly to my Diamondback hybrid frame, and the chain kind of bounces when the clutch is engaged. I wasn't having this problem before, it suddenly started happening.
