Have 1993 Yamaha Waverunner. Engine runs very good, but after riding, if it sits a while takes a lot of cranking to get it started again. Have used starting fluid (with oil included in the fluid to avoid burning top of piston) and it starts up. Somehow I think the gas left in the carb leaks down when it is idle for a while. I understand there is a small diaphragm in the carb that oscillates when the engine is turning over with the starter that is supposed to pump the gas from the tank back into the carb. Seems this diaphragm is not working properly. Any comments from forum members would be appreciated.
