i thought i fixed my problem, i changed my spark plugs. 1 was real black and sooty and the other was ghost white. how can one cylinder be running rich and the other lean? the new plugs def. helped with idling, but didnt solve the motor bogging problem. if i am mowing down hill, it dont bog, but if i am level or going up hill, once i apply the gas pedal, it starts dieing down till i have to stop and wait for it to catch up. i thought the vacuum actuator was bad slowing the blades down, but its def the motor. to test this theory, i turned the blades off and went full throttle across the yard. halfway across, the motor nearly stalled and died. any fixes to this problem without going to a cub service dealer or small engine repair shop?
