FAQS
Cold Start
- Add fuel (fuel mixing ratio: 25:1).
- Close the choke. If the machine is equipped with a primer bulb, press it 3–5 times until the bulb is filled with fuel.
- Pull the starter rope 3–5 times.
- After hearing two “coughing” sounds,
- Open the choke.
- Pull the starter rope to start the machine.
Hot Start
- Open the choke.

The issue may be caused by an incorrect fuel mixture, spark plug problems, or a clogged carburetor.
- Check whether the fuel mixing ratio is 25:1. If not, adjust the fuel mixture to 25:1.
- Check whether the fuel line is bent or blocked.
- Check whether the spark plug is sparking properly.
- Check whether the engine is flooded.
- Check whether there is a carburetor malfunction.
- Confirm whether the spark plug is producing a spark: Remove the spark plug, connect it to the ignition coil, and place the spark plug electrode in contact with a metal part of the machine. Pull the starter rope and observe whether the spark plug produces a spark during starting.
- Check the electrode gap. The correct gap is 0.5–0.7 mm (approximately the thickness of a credit card).
- Clean oil residue and debris from the surface of the spark plug.
- If the engine still does not start after completing the above steps, replace the spark plug with a new one.
- Check whether the high-voltage wire (ignition coil lead) is damaged.
- Remove the spark plug.
- Turn the machine upside down.
- Pull the starter rope.
- Drain the excess fuel from the cylinder.
- Remove the air filter.
- Use an air blower to remove dust or debris from the air filter.
- If it cannot be cleaned or has been used for a long time, replace the air filter.
