First check if there is enough gasoline in the fuel tank, then check if there are any problems with the supply to the carburetor and fuel pipe.
2. If there is no problem with the above, look directly at the spark plug, ignition coil, igniter and high voltage assembly. The spark plug may have fallen out or the spark plug head is not tightened enough.
3. Caused by battery loss. When starting, use the electric starter for a while (fully charge the battery first) or turn off the key and start with your foot a few more times.
4. The motor is leaking air. The combustible gas must be burned and compressed in a closed space to ensure proper engine operation.
Hello. The pictures shown above are all high voltage packages. Each high voltage assembly can be used normally when itis placed on a motorcycle. Only the appearance is different. The operating principle is the same. The one with the green wire belongs to the positive terminal. I took three screenshots separately. The one with the red arrow is the positive terminal. The outer shell of the high voltage box is the negative electrode.
