Troy-Bilt Pressure washer starts then stalls
When your Troy-Bilt gas pressure washer starts then stalls, the most likely cause is a clogged carburetor. Stale or ethanol-blended fuel left in the carburetor during storage can evaporate and leave sticky deposits that restrict fuel flow, causing the engine to start and stop, start then die, or shut off after a few seconds. Clean the carburetor with carburetor cleaner first. If that does not solve the problem, replace the carburetor or install a carburetor repair kit. A clogged fuel filter is another common cause, especially when old fuel remains in the fuel tank, so drain the tank and replace the filter. Next, check the fuel cap. A blocked cap vent can create a vacuum in the tank and stop fuel from reaching the carburetor. Loosening the cap slightly can help confirm the problem. A clogged air filter can also restrict airflow and cause the engine to stall, while a clogged pre-cleaner is possible but less common. Whether your pressure washer starts then stops or will not stay running, enter your model number to find the exact replacement part for your specific Troy-Bilt pressure washer.
01 - Troy-Bilt 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.

Highly Likely
04 - Troy-Bilt 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 - Troy-Bilt 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 - Troy-Bilt Pressure Washer Pre-Cleaner
The pre-cleaner might be clogged. However, this is rare.
Highly Likely
