I have a 2004 Yamaha V Max 200 HP. After I fish in 95-95degree weather for 30-40 minutes, I have to try cranking the engine three or four times before enough gas gets back up into the carburetor. I have tried a new bulb and a new fuel line assembly connecting to the fuel intake at the engine. Same problem. Do you have any suggestions of how to correct this problem? Thanks, Greg Williams
