Why won't my Qidian KD-150 start?
2 Answers
There are several reasons why a Qidian KD-150 motorcycle won't start: Fuel line blockage: If the fuel line is blocked, check the drain screw at the bottom of the carburetor. If fuel flows out when unscrewed, there's no issue; otherwise, the fuel line needs clearing. Insufficient engine compression: For insufficient engine compression, step on the kick starter to feel resistance. If there's no resistance, the engine may be damaged and require overhaul. If resistance is felt, this can be ruled out. Spark plug inspection: Check the spark plug, as this is the most common cause of starting failure. If it's blackened or the spark is weak, it's likely damaged and should be replaced to resolve the issue.
Last month, my Qidian KD-150 suddenly wouldn't start either, and I was really anxious at the time. Fortunately, experience told me the battery might be dead, so I took out the charger to give it a try, and sure enough, it started right up after charging. Besides battery issues, common causes include aging spark plugs or faulty ignition coils. I've encountered excessive carbon buildup on spark plugs before, and cleaning them made a big difference. On the fuel supply side, clogged fuel injectors or an empty tank can directly prevent starting—always check the fuel gauge first. Also, cold weather makes starting harder, and with lower engine temperatures, it's especially important to check if the air filter is blocked. A simple blast with an air gun can often solve that. If these basic fixes don't work, don't push your luck by trying to push the car to the shop—getting a professional diagnosis is both safer and more reassuring.
