I recently rebuild a banshee and completely went through and rebuilt the carbs. I read a few topics on here where people had this same problem but didn't see a documented solution. The choke carb has the correct bowls, the middle plastic tube is present, the floats are 21mm without gaskets, and the slides are facing the correct way. The banshee will not start without spraying gas in the carbs. Once it starts it runs great with plenty of power. Fatty pipes with no air box lid. Main jet is 310 and pilot is 25 at 1 turn out.
Obviously the bike is not drawing fuel on startup. Compression is good.
Any suggestions would be great.
