How to Solve the Problem of a Scooter Not Starting?

If a scooter has both electricity and fuel but still won't start, the most likely cause is an issue with the ignition system. Sometimes, wiring problems can also prevent the scooter from starting. When the cause is unknown, we can try kick-starting the scooter.
I've been working with motorcycles for over a decade. When a scooter won't start, you basically just need to check three things: the battery, spark plug, and fuel system. A dead battery is the most common issue - if the horn doesn't sound or the headlight is dim, that's usually the culprit. Just jump-start it or replace the battery. If the starter motor spins happily but the engine won't catch, there's an 80% chance the spark plug is dead - take it out and check for carbon buildup or electrode erosion. Older carbureted bikes are especially prone to clogged fuel lines - try starting with the choke on. Oh, and for scooters with kill switches, don't forget to check if the switch has returned to position. My neighbor once had to push his bike for half an hour because of that, haha.
Last year my scooter wouldn't start either, so I've summarized a few DIY troubleshooting tips for beginners. First listen for sounds: If there's no response at all, first check if the battery terminals are loose; if you hear a 'click-click' from the starter motor but the engine won't turn over, it might be a faulty starter relay; if the starter motor spins normally, then check the spark plug and fuel supply. Remember to verify if the fuel valve is switched to ON - for older scooters, you might need to twist the throttle a few times to let the carburetor pump fuel. Last week my bike wouldn't start after getting rained on, and simply using a hairdryer to dry the spark plug cap fixed it. If all else fails, don't force the starter motor - pushing it to the repair shop is much cheaper than replacing a starter.
