Sleeve gear bushing okay?
Easy test, keep a feel on primary chain tension while putting tension on drive chain with foot or assistant. If primary chain tightens up when pressure put on drive chain, replace sleeve gear bushing (easier said than done, sometimes).
Probably NOT this but so easy to check, why not? :?
