I got a hell of a deal on this bike ($500) from a family member yesterday. One dent on the bike and I did that trying to get it out of his truck in the rain! Anyway, I canĀ“t get fuel out of the carb that feeds the rear cylinder. The floats are working, no holes in the diaphram, and I removed the main jet @ seat and cleaned them. Is there another part of that carb I need to check? It will start and idle on the front cylinder. It hasnt been started in three years.
