Common solutions for: Pressure washer runs rough
Solution 1:
Carburetor
The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the pressure washer for a long period of time. Over time, some of the ingredients in the fuel may evapo...rate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to run roughly. If the carburetor is clogged, try cleaning it with carburetor cleaner. If cleaning the carburetor isn’t effective, rebuild or replace the entire carburetor.

Solution 3:
Fuel Cap
As fuel is consumed, the pressure in the gas tank rises. To relieve this pressure, the gas cap uses a small vent to allow air to enter the gas tank. If the gas cap vent is clogged, air won’t be able t...o enter the gas tank, and the pressure in the tank will begin to rise. When the pressure in the gas tank exceeds the pressure in the engine, the engine will stall or run poorly. To determine if the gas cap vent is clogged, try slightly loosening the gas cap and then starting the engine. If the loosening the gas cap allows the engine to stay running, this indicates that the gas cap vent is clogged. If the gas cap vent is clogged, replace the gas cap.
