What causes a scooter to fail to start after being exposed to rain?
1 Answers
Scooters failing to start and accelerate after being exposed to rain are generally caused by water entering the air filter, fuel tank, or carburetor, or moisture affecting components such as the ignition coil, high-voltage coil, high-voltage wire, spark plug cap, ignition switch, and ignition system wiring. Common reasons for starting difficulties in scooters include: Fuel system issues: Primarily due to a faulty fuel valve (no fuel flow), clogged fuel filter, carburetor issues (no fuel flow or overly rich mixture), or bent fuel lines. Electrical system issues: Short circuits in electrical components (e.g., ignition switch, high-voltage coil, ignition coil, or magneto failure) or open circuits caused by loose wiring harness connectors. Air pressure issues: Insufficient cylinder compression, improper air filter resistance, or engine intake/exhaust faults.
