      If your Qianjiang Scooter's spark plug has no flashover, the issue could stem from several causes. Begin by replacing the spark plug with a new one and testing again. Ensure the spark plug is properly installed and there's no slack. Check for bad contact of the plug and correct the connections. Other potential causes include a broken main switch (replace it), a faulty charge coil (inspect and replace it), or a bad sparking coil (inspect and replace it).

      Improper charging in your Qianjiang Scooter, whether overdischarge or overcharge, can be due to several reasons. If there's no increase in battery voltage, check the voltage regulator wiring connection. A slack voltage regulator plug should be fixed. If the battery voltage is higher than normal, again check the voltage regulator wiring. A bad battery should be replaced. Also, inspect the red and white wiring lines for open circuits. Finally, ensure proper connections and grounding of the wiring to rule out imperfect earth.

      If your Qianjiang Scooter is hard to start, several factors could be the cause. Begin by checking if there is gasoline in the tank and whether the carburetor has oil. Inspect the oil tube and conduit of the evaporation control system for any clogs. A clogged gasoline filter can also be the culprit, so replace or clean it. Other potential issues include a broken auto oil ring (replace it), a faulty spark plug (replace or clean it), or a broken CDI group (replace it). Also, check the trigger, sparking coil leads, and sparking coil for any breaks or shorts. Finally, the main switch, piston, piston ring, and cylinder head should be inspected for damage or leaks. Other possible causes include bad auto choke actuation, intake air issues, incorrect ignition time, overhigh oil level of carburetor,...

      If your Qianjiang Scooter is experiencing improper gyration, several factors could be the cause. Low compression pressure could be the issue, start by inspecting the air cleaner. A clogged air cleaner may also be the reason, so clean or replace it. Ensure you're using good quality gasoline. Inspect the conduit of the evaporation control system of the firing chamber for any blockages. Also, check for a clogged exhaust pipe. Other potential issues include a faulty auto choke (check or replace it), incorrect ignition time (adjust it), or a broken auto oil ring (replace it). If the compression pressure is normal, inspect the piston and piston ring. Bad timing adjustment can also cause this, so adjust the timing properly. Other possible causes include a clogged carburetor (clean it), a polluted...
