What Are the Reasons for a Scooter Making Noise but Not Moving When Throttling?

[DiLuna]

The reasons for a scooter making noise but not moving when throttling are as follows: 1. Spark plug failure: Excessive carbon buildup on the spark plug or an overly rich air-fuel mixture can cause the spark plug to malfunction. In this case, cleaning or replacing the spark plug will resolve the issue. 2. Wiring failure: Aged or leaking high-voltage wires can prevent the spark plug from functioning properly. Replacing the high-voltage wires with qualified ones will solve the problem. 3. Ignition system failure: A faulty ignition system can cause the spark plug to malfunction. Replacing the ignition system with a qualified one will address the issue.
