Hi, i just bought a used 8hp nissan. It starts fine at first, runs good but after 10 min. it supters out and will only start when i turn the gass up all the way runs for a min. and the same thing again. the lower is hot and there is no water coming from the pee hole at all. i have looked at the carberater it looks clean. the fuel felter was dirty so i replaced it.<br /><br /> Is it the water pump or more thanks for help.<br />aaron
