Briggs & Stratton Pressure washer starts then stalls
If your Briggs & Stratton gas pressure washer starts then stalls, the carburetor is the most likely problem. Stale or ethanol-blended fuel left in the carburetor during seasonal storage can evaporate and leave sticky deposits that restrict fuel flow. Clean the carburetor with carburetor cleaner, then rebuild or replace it if cleaning does not help. A carburetor repair kit may include the needed gasket, needle valve, and other components. Next, check the fuel filter, which can also clog after old fuel sits in the fuel tank, and replace it after draining the stale fuel. A blocked fuel cap vent can create a vacuum in the tank and cause the pressure washer to start and stop, so try loosening the cap briefly. If the engine still will not stay running, inspect the air filter and pre-cleaner for restricted airflow. These faults can cause a pressure washer to start then die, run for only a few seconds, or keep shutting off. Enter your model number to find the exact replacement carburetor, fuel filter, fuel cap, air filter, or repair kit for your specific Briggs & Stratton pressure washer.
01 - Briggs & Stratton 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 stall. If the carburetor is clogged, try cleaning it with carburetor cleaner. If cleaning the carburetor isn’t effective, rebuild or replace the entire carburetor.

03 - Briggs & Stratton Pressure Washer Fuel Filter
The fuel filter might be clogged. A clogged fuel filter is most commonly caused by leaving fuel in the pressure washer for a long period of time.

Highly Likely
04 - Briggs & Stratton Pressure Washer Fuel Cap
As fuel is consumed by the engine, the level in the fuel tank lowers. To make up for this, the fuel cap uses a small vent to allow air to enter the tank. If the fuel cap vent is clogged, air won’t be able to enter the tank and a vacuum or “vapor lock” will occur. This stops the flow of fuel to the carburetor causing the engine to stall. To determine if the fuel cap vent is clogged, try slightly loosening the cap and then starting the engine. If loosening the fuel cap allows the engine to stay running it is likely clogged and will need to be replaced.
Highly Likely
05 - Briggs & Stratton Pressure Washer Air Filter
The air filter may be clogged. If the air filter is clogged, the engine will get too much fuel and not enough air. As a result, the engine may stall. If the air filter is clogged, replace it.
Highly Likely
06 - Briggs & Stratton Pressure Washer Pre-Cleaner
The pre-cleaner might be clogged. However, this is rare.
Highly Likely
