Re: Does the carb have to be perfectly level?
I was mistaken, It wasn't in that thread. It was in another one that I stumbled on when I was doing a search on chain alignment. I tried to find it and no luck.
It was a rear engine mount that clamped onto the seat tube and sort of had a hinge inbetween the clamp and the engine. It would allow you to swivel the rear of the engine left or right. If you swivel the engine to the left then you could have more clearance for the chain to miss the tire and be in better alignment with the sprocket.
