Is this a natural gas fueled generator? Sounds like a fuel problem, i would go through the fuel system and find out whats wrong. If its a natural gas/propane unit its most likely a bad regulator or low pressure.

Surging


It definately sounds like a fuel problem, lack of fuel..I assume it is running on LP or natural gas. The hose running from the demand regulator goes to the carburetor/mixer. When it gets to the carburetor, there is an adjustable main jet. It is different on different models, but is usually easy to find. There is probably a screw slot in the end of the screw head and a spring under the head. Start it up after locating the screw and open the jet just enough to even out the running. It was factory set, but barometric pressure and altitude and different fuels in different areas will decessitate different settings.
Please let me know if this fixes your problem, Robert

Small 7kw Generac has always sounded rough over the three years we've had it. Oil and plug are fine but lately, after warmup, engine seems to misfire and eventually shuts off during the normal weekly test...


If the generator is out of warranty, you can try spraying a short shot of ether into the intake of the generator as it is running rough. If the engine smoothes out for a few seconds, and returns back to original state, then it is likely running lean. Check the gas regulator (this is LP or natural gas I am assuming since it is standby), the vent may be clogged on the bottom of it.
