It started out running great,ran it for 3 hours with no problem. slowed down to a trolling speed about 5hps and it killed. But ran great again at high speed. Well today I had it wide open and it would only do like 10hps. and once in a while take off going about 40. Anybody have any ideas?<br /><br />I need of help<br /><br />Mike

Whenit slows down squeeze the bulb in the fuel line a few times. If it speeds up you have a fuel system problem (blockage, air, fuel pump, carbs etc.).
