I will check the carb attachment and the jet. I also have a new rubber bushing that i'll replace while I'm at it.
Would bad timing cause the symptoms I've described? It runs evenly and consistently up to 14mph, it starts on a dime, it revs while on its stand with no irregularity, etc.
How do you know if the throttle cable is tight enough? I've adjusted to the max with the adjustment nut, but I'm thinking I could loosen and pull the cable through further.. Thoughts?
