Echo Pressure washer runs rough
When your Echo gas pressure washer is running rough, surging, sputtering, or hesitating, start with the carburetor. Stale or ethanol-blended fuel left in the carburetor is one of the most common causes of rough operation in seasonal equipment. Evaporated fuel can leave a sticky residue that clogs the carburetor's passages, so clean it with carburetor cleaner. If cleaning does not solve the problem, rebuild or replace the carburetor, or install a carburetor repair kit. A clogged fuel filter is the next likely cause, especially if old fuel remains in the fuel tank. Drain the tank and replace the fuel filter. A blocked fuel cap vent can also restrict airflow into the tank, causing the engine to run poorly or stall. Loosen the cap slightly while testing, and replace it if performance improves. Next, inspect the air filter, which can make the pressure washer engine run rough when it is clogged. Replace the air filter, and check the pre-cleaner as well, although it is less commonly responsible. Enter your model number to find the exact replacement part for your Echo pressure washer.
01 - Echo Pressure Washer 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 evaporate, 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.

04 - Echo Pressure Washer 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 to 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 clogge...
