Why won't my QUADRO VEHICLES Qooder Scooter engine start?
- LLeslie CollinsAug 4, 2025
Your QUADRO VEHICLES Scooter engine might not start due to several reasons: the engine stop command may not be in the correct position, the brakes might not be activated or the brake switch could be defective (operate the brakes, and if necessary, consult a qualified workshop), the fuel tank might be empty (check the fuel level), the spark plug could be dirty, the air or fuel filter could be clogged, the engine could be clogged (remove the spark plug and vaporize fuel inside the cylinder, then consult a qualified workshop), or a fuse might be blown (replace the fuse and have the vehicle checked by a qualified workshop).
