Re: KF5 " When I get close to top speed it starts to crap out"

Check fuel flow by disconnecting the fuel line from the carb or tank and see if the flow is adequate and continuous. Not sure but I think that motor has a fiber fuel filter inside the tank. They are frequently fouled with ancient oil, shellac, rust, etc, and will pass fuel okay for low speeds but not enough at high speeds. Look under the starboard rear of the tank for a BIG nut, which is the filter. Takes a large wrench and muscle to remove. Also can shine a small flashlight thru the fill hole and see the filter. Good luck. They are great little motors. JW
