What's the reason for Cummins engine throttle not accelerating?
1 Answers
Cummins engine throttle not accelerating could be caused by a lean air-fuel mixture or lack of warm-up after starting. If this condition disappears after the engine warms up, it should be this situation. The name of this phenomenon: This phenomenon is called high-speed misfire, which means the spark plug doesn't fire continuously at high RPM, resulting in high-speed hesitation or inability to reach high speed. Solution: Clean the carburetor and adjust the air-fuel mixture to normal. If necessary, adjust the height of the fuel needle. It's best to fully warm up the engine after starting before driving. This can not only avoid this situation but also protect the engine and reduce wear during startup.
