How to solve the problem of a scooter not starting?

Before starting, first check whether the motorcycle switch is turned on and whether there is gasoline in the fuel tank. Check whether the ignition advance angle is correct. If the ignition advance angle is correct, it means there is no problem with the high-voltage ignition system. Then, the issue should be considered from the fuel system. If a spark of 5~8 mm is generated between the spark plug and the cylinder body, but no spark is produced between the center electrode and the side electrode of the spark plug, it indicates that the ignition circuit is normal. If the length of the spark generated between the spark plug and the cylinder body is only 2~3 mm, it is necessary to first check the gap of the breaker's platinum contacts.
As a long-time scooter enthusiast with over a decade of riding experience, I've encountered numerous starting issues. The most common culprit is a dead battery, especially in cold weather when power drains quickly. Check for loose or corroded battery terminals and try charging it for a while. Spark plugs are another frequent problem – remove them to inspect for carbon buildup, then clean or replace as needed. Don't overlook the fuel system; open the gas cap to listen for a hissing sound, and refuel immediately if empty. For ignition issues, sometimes it's just poor wire contact – try tightening the connections. I remember one rainy ride when the scooter wouldn't start because the spark plug got wet – drying it solved the problem instantly. For prevention, monthly checks of battery charge and fasteners are essential, and avoid prolonged parking in damp conditions. If DIY solutions fail, it's best to take it to a professional mechanic rather than risk engine damage.
