How to troubleshoot a Briggs & Stratton 12KW that won't start?
- RRaymond HernandezAug 19, 2025
If your Briggs & Stratton Portable Generator engine won't start, or starts and runs roughly, consider the following: 1. Check if the 15 Amp fuse is missing or blown. Install a new 15 Amp fuse. 2. Thermal fuse(s) might be blown. Replace them. 3. Ensure the fuel supply is turned on and not depleted. Open the fuel valve(s) and check the propane tank. 4. Verify that the fuel selection is correct using the fuel selector switch. 5. A failed battery can prevent starting. Replace the battery. 6. A clogged air filter can cause starting issues. Clean or replace the air filter. 7. Check for any binding in the throttle linkage.
