I just got it so don't know anything about the history. It starts and runs if I carefully manage the throttle, but makes horrible bangs and pops and backfires. It has fresh gas. I figure it must be something either with the timing or the dual carburetors not being balanced. Are one of those ideas right?
The oil is full, just changed, but, yes, the exhaust is rusted off so one of the cliders is just going out into a short pipe about 8 inches long. Back pressure problems?
