My problem is that my RPM's surge, it would run @6500 and then wouldnt go above 4000 at WOT. It has gotten worse and wont go above 3500-4000. new carb rebuild with good pop-off and even switched carbs with other engine,same thing! Pulse line is clean, cleaned fuel valves and switched them out, same thing! Pulled red wire on rectifier and even switched them , same thing! bypassed rev limiter, new fuel lines put in with new inline filters, clipped plug wires back, same thing. engine runs good on land but in the water under load is a different story, and I noticed also the pee hole doesnt piss so well ( not like the other engine) I had the exhaust off (no restictions), tuned pipe has no restrictions (water or exhaust), while the engine was running I did notice the bottom half side of the tuned pipe was hot while the rest of the pipe was cool, even at the manafold end it was cool, could the tuned pipe be leaking and water being sucked into pistion chamber? Help I'm going crazy:ack:
