  If your Briggs & Stratton Portable Generator runs well with no load but bogs down when loads are connected, consider the following possibilities: 1. The generator may be overloaded. Try removing one or more loads. 2. There might be a short circuit in a connected load. Disconnect the shorted electrical load. 3. The fuel pressure or mixture could be incorrect. Consult the installation manual's Gaseous Fuel System section. 4. A kinked fuel line between the regulator and engine could be the problem. Remove the kink, and replace the fuel line if necessary. 5. For a shorted generator circuit or an Electronic Governor system not operating properly, contact a local service facility.
