Possible Causes
Fuel supply turned off or insufficient gas pressure, Clogged carburetor jets, Fouled spark plugs, Air in fuel line after service
How to Fix / Troubleshooting
Safety first: Disable automatic start and keep clear of moving parts. Avoid open flames near fuel.
- Confirm fuel supply: Verify LP/NG shutoff valves are open and other gas appliances in the home operate normally.
- Prime and purge: Some Briggs & Stratton models require several crank cycles to purge air after gas work. Attempt multiple short crank cycles with rest periods to avoid overheating the starter.
- Inspect spark plugs: Remove plugs, check for wet fouling or heavy carbon. Clean or replace with correct Briggs & Stratton plugs and gap.
- Clean carburetor: Remove the carburetor bowl and clean the main jet and passages with carburetor cleaner and compressed air. Reassemble with a new bowl gasket if needed.
- Retest in MANUAL: After reassembly, attempt a manual start and monitor for normal operation.
