Craftsman Pressure washer starts then stalls
If your Craftsman gas pressure washer starts then stalls, the carburetor is the most likely problem. Stale or ethanol-blended fuel left in the carburetor can evaporate and leave a sticky residue that restricts fuel flow, causing the pressure washer to start and stop or run for a few seconds before dying. Clean the carburetor with carburetor cleaner, then rebuild or replace it if cleaning does not restore operation. A clogged carburetor repair kit may also need replacement. Next, check the fuel filter, especially if old fuel was left in the tank, and drain the tank before installing a new filter. A clogged fuel cap vent can create a vacuum in the tank, so briefly loosening the cap can help confirm this problem. A dirty air filter or, less commonly, a clogged pre-cleaner can also starve the gas engine for air and make the pressure washer shut off after a few seconds. These checks address common reasons a pressure washer starts then dies or won't stay running. Enter your model number to find the exact replacement carburetor, fuel filter, fuel cap, air filter, or other part for your Craftsman pressure washer.
01 - Craftsman 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.

Highly Likely
04 - Craftsman 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 - Craftsman 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 - Craftsman Pre-Cleaner
The pre-cleaner might be clogged. However, this is rare.
Highly Likely
