Portable Generator Repair

Portable generators require routine maintenance and repair.

Most portable generator use a 4 stroke gas engine to run the generator and produce power. A 4 stroke engine needs 3 things to start and run properly – air, fuel and spark. If one of these is missing, the engine will not run. Most engine issues are the due to the lack of one of these elements.

Portable Generator Repair Tip: Fuel

Fuel is obviously important. If you suspect that your engine in your portable generator is not getting enough fuel, there are a few thing you do.

First, make sure that you are using good gas that hasn’t been sitting in the tank. Old gas can cause the engine to run rough.

If the engine isn’t starting, check the vent hole on top of the gas cap. The vent allows the fuel to flow into the carburetor. If it is clogged, fuel will not be delivered to the engine.

If it still fails to start, it may be due to a bad or clogged fuel pump or carburetor. Check out this youtube video that shows how to properly clean a small engine carburetor.

Replace or clean (if it isn’t too dirty) your air filter to keep your engine running tip top.

If it is not working properly, it can cause the engine to run rough or not run at all. Check the spark plug for wear and corrosion. A white or tan spark plug may indicate that you engine

Make sure you clean or replace a spark plug that is dirty or highly worn.
