Engine has ran fine. Went to lake fishing, statred the engine a few times to move around to my favorite fishing spots. Time to come home, engine would not start. Act like the plugs were not firing. I dont't use the kill switch so this should not be the problem. After about six hours,<br />and using a water hose connector, I removed the top plug to see if I could see a spark. The motor started instantly on two plugs. I replaced the top plug and again the motor started instantly. Whats the problem?<br /><br /> The Pirate
