Re: Drive chain sprocket
I've had the same problem. If the chain is rubbing against housing you need to grind down housing a little. It may also be rubbing against housing because the teeth on the sprocket are not seated. Lay your chain on a flat surface, take your sproket and roll it down the chain. If it pulls the chain up, grind the corners off the teeth a little. Do this until the sproket runs freely through the chain.
