What are the reasons why the Qidian 150 won't start?
2 Answers
Reasons why the Qidian 150 won't start are as follows: Fuel line blockage: There is a drain screw at the bottom of the carburetor. If oil flows out when the screw is loosened, it indicates no problem; otherwise, the fuel line needs to be cleared. Insufficient engine pressure: Step on the kick starter with your foot to feel the resistance. If there is no resistance, it means the engine is damaged and requires an overhaul. If there is resistance, this can be ruled out. Spark plug damage: Check the spark plug, which is also the most common reason for failure to start. If it is blackened or the spark is weak, it is damaged and can be resolved by replacement. Dead battery: Failure to start may be due to a drained battery caused by leaving the headlights on for a long time or the battery reaching the end of its lifespan. It is generally recommended to replace the battery every 2 years.
I previously encountered a starting issue with my Qidian 150, and the most common causes were a dead or aging battery. After riding for a while, the battery might be completely drained or have loose connections, preventing the starter motor from turning. Another possibility is a faulty spark plug—excessive carbon buildup can lead to poor ignition, resulting in just a clicking sound when pressing the start button. Fuel system problems could also be to blame, such as an empty fuel tank or a clogged carburetor, which prevents fuel from reaching the engine and thus causes failure to start. Additionally, a blown fuse or a damaged relay can cause a short circuit, disrupting the entire electrical system. I make it a habit to regularly check the battery voltage and clean the spark plugs. Usually, replacing the battery myself or refueling solves the problem. Extra attention to battery maintenance is needed after long periods of inactivity to avoid issues while riding—safety always comes first when on a motorcycle.
