Why does my Briggs & Stratton 12KW Portable Generator engine bog down under load?
- A
  Amanda RobinsonAug 23, 2025
  If your Briggs & Stratton Portable Generator engine runs well without any load but falters when loads are connected, there could be several reasons: 1. The generator might be overloaded. Try removing one or more loads. 2. There could be a short circuit in a connected load. Disconnect the suspected electrical load. 3. It's possible there's a shorted generator circuit, in which case you should contact a local service facility. 4. The fuel pressure or mixture might be incorrect; consult the Gaseous Fuel System section in the manual. 5. A kinked fuel line between the regulator and engine could be the culprit. Remove the kink, and replace the fuel line if necessary. 6. Lastly, a clogged air filter could be restricting airflow. Clean or replace the air filter.
