Remove starter from engine and spray the pinion with methylated spirit ,dry it off then spray with graphite lube.

1. Fuel System Issues:
   • Check the fuel system for clogs, such as a dirty fuel filter or carburetor jets.
   • Ensure that the fuel tank and fuel lines are clean and free from debris.
   • Consider adding a fuel system cleaner to help clean out any deposits.
2. Ignition System Problems:
   • Inspect the spark plugs for fouling, wear, or improper gap.
   • Check the ignition timing to make sure it's set correctly.
   • Inspect the ignition coils and wiring for any loose connections or damage.
3. Air Intake and Exhaust Issues:
   • Examine the air filter for clogs or dirt that may restrict airflow.
   • Inspect the exhaust system for any leaks or blockages.
4. Vacuum Leaks:
   • Check for vacuum leaks in hoses, gaskets, or intake boots. A vacuum leak can cause an improper air-fuel mixture, leading to backfiring.
