Hey guys so I purchased a 78 Yamaha xs750 late June which was running fine and hasn't ran since then. I did some work which included a carb rebuild and now I get it to try to turn and almost hear it turn with the engine almost coming to life. I do believe it's the carb since I have done all tests for other problems (compression, spark, and starter) but I don't know what to do with the carb since I think I have it all perfect. The carb for reference is a Mikuni mk ii bs34 if I'm not mistaken. I have recently ordered new jets that the manual recommended a 145 main jet and a 42.5 pilot jet, not recommend by the manual due to the size not being on jetsrus but I'm using their recommendation for my specific bike. Any idea on how to get the carb to working order again? Thanks guys.
