It acts like it's running out of gas then clears up. It started end of season last year. I changed gas and the bulb this year also cleaned pick up screen in the gas tanks. I have 2 6ga tanks. I can sit at dock for 10 min WOT then go out and run around then slugs right down and stalls at times. Will start right up but real low idle then clears up. Forgot put a new filter on also. TIA
