2. Inspect the carburetor:
- Cleaning or rebuilding dirty or clogged carburetors may be necessary.
3. Test the ignition system:
- Check the spark plug wire to ensure it is properly attached to coil.
- Remove the spark plug and check for a spark when cranking the engine.
- If there is no spark, replace the spark plug or check ignition components like ignition coil, CDI box, or stator.
4. Examine the air filter:
- Clean or replace a clogged air filter.
5. Verify the throttle cable is functioning correctly:
