When you want to wash something with your engine-powered pressure washer and it won't start or it won't stay running, you have to diagnose the problem. If the engine's spark plug is good, it has plenty of gas and the air filter is clean, then there is a good chance that the carburetor on the engine is dirty and clogged. A clogged carburetor prevents gas from getting to the engine, so you will have to unclog it.
Things You'll Need
Pliers
Bucket
Carb cleaner spray
Locate the gas line between the gas tank and the carburetor on the pressure washer engine. This line is usually a thin, flexible tube.
Pinch the clamp on the carburetor end of the gas line with your pliers and slide the clamp down the hose several inches.
Pull the hose off and direct the old gas into the bucket. Spray carb cleaner into the carburetor hole for five to six seconds. Reconnect the gas line to the carburetor.
Unscrew the fuel bowl on the base of the carburetor with the pliers. Dump out the old gas from the fuel bowl into the bucket. Spray carb cleaner into the bowl to remove any debris.
Look above the fuel bowl on the float and valve. This is where the clog usually is. Wipe away any big debris with your finger. Spray carb cleaner onto the float and butterfly valve above the fuel bowl to remove any clogs.
Insert the canned air nozzle above the float and into the butterfly valve hole and spray for ten seconds.
Screw the fuel bowl back on.
