Cub Cadet Pressure washer starts then stalls
When your Cub Cadet gas pressure washer starts then stalls, the most likely cause is a clogged carburetor, especially when stale or ethanol-blended fuel has been left in the carburetor during seasonal storage. Old fuel can leave a sticky residue that restricts fuel flow and causes the engine to die. Clean the carburetor with carburetor cleaner, then rebuild or replace it if cleaning does not solve the problem. A clogged carburetor repair kit may also need replacement. Next, check the fuel filter and drain old fuel from the fuel tank before installing a new filter. A clogged fuel cap vent can create a vacuum in the tank, so loosen the cap slightly and restart the pressure washer. If it stays running, replace the fuel cap. A clogged air filter can also restrict airflow and make the engine stall, while a blocked pre-cleaner is possible but less common. These checks address common symptoms such as a pressure washer starts then dies, pressure washer starts then stops, pressure washer won't stay running, or pressure washer shuts off after a few seconds.

01 - Cub Cadet 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.

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