Hello<br />I was cruising for 3 hours @ 5000 rpm, when I hear a muffle noise ... the engine slow down and stop. I started again, but this time it was making explosions coming out the carburator and run for 50 feet and die; started again and have my brother pumping the gas line continuos, until we got to a safe place. I thinking that maybe is the fuel pump or water on the carb. due to a heavy rains during the week. It will run.. if we keep pumping the fuel line continuos @ full trottle, but the rpm are reading @ 2000.<br />Any suggestions will be appreciated.<br />RiverMan :eek:

Fuel pump. A rebuild kit is very cheap and it only takes minimal time to rebuild it. If your motor has not been done since new...I would suspect that first.<br /><br />I just recently replaced my primer bulb that finally gave way to old age and weather so I would not be surprised if the fuel pump diaphram went.<br /><br />Bob
