I'm having trouble giving my engine throttle after a period of idling. When I turn the engine off and back on - I'm able to take right off with full speed and it runs fine. I'm baffled. The engine appears to idle fine. My first trip out this year, I could not get up on a plane at all. It seemed to be bogging down and having trouble getting fuel. So, I replaced the spark plugs, in-line fuel filter and the engine mounted fuel filter. The engine mounted fuel filter had a lot of popcorn kernel looking debris which turned out to be coming from an 8" piece of grey fuel line next to my bulb... which I replaced. I also put some SeaFoam in my tank. The engine is running much better; however, if I'm idling for a few minutes I still get the bogging down when trying to throttle up. Any ideas??? I'm thinking it could be a stuck float in the fuel injection pump.
