The motor starts easy, idles good, transitions from idle to upper rpm with no stumbling or bogging and runs good at upper rpm. Here's the problem. After I travel a distance, lets say about 5 minutes at 1/2 or better throttle and I throttle back to an idle the motor will idle fine but if I then advance the throttle to pick up a little more speed it starts to stumble and cut out.
Any help would be greatly appreciated.
