Causes of difficulty in starting rope gasoline engine.

Fuel problem, spark plug problem, air filter problem, throttle problem, nozzle problem.

1. Fuel problem: check whether the fuel is sufficient, whether the fuel quality is good, and whether the fuel pipeline is blocked or leaked.

2. Spark plug problem: The spark plug is dirty, worn or the gap is incorrect, resulting in poor ignition. Cleaning or replacing the spark plug can solve the problem.

3. Air filter problem: air filter blockage will limit air flow and affect the normal combustion of the engine. Clean or replace the air filter.

4. Throttle problem: The throttle is stuck or broken, resulting in abnormal airflow. Check and clean the throttle.

5. Nozzle problem: The nozzle is blocked or faulty, resulting in uneven or insufficient fuel injection. Clean or replace the fuel injector.
