Homelite Pressure washer starts then stalls
When your Homelite pressure washer starts then stalls, the most likely cause is a clogged carburetor. Stale or ethanol-blended fuel left in the carburetor during seasonal storage can evaporate and leave sticky residue that restricts fuel flow, causing the pressure washer to start then die or run for only a few seconds. Clean the carburetor with carburetor cleaner first; if that does not restore steady operation, install a carburetor repair kit or replace the carburetor. Next, check the fuel filter, which can also become clogged by old fuel, and drain the fuel tank before replacing it. A blocked fuel cap vent can create a vacuum in the tank, so briefly loosening the cap can help identify this problem. If the engine still will not stay running, inspect the air filter and replace it if it is dirty or clogged. A clogged pre-cleaner is possible but less common. These checks apply to the gas engine and fuel system on Homelite pressure washers. Enter your model number to find the exact replacement carburetor, fuel filter, fuel cap, air filter, or other part for your specific pressure washer.
01 - Homelite 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 - Homelite 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 - Homelite 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 - Homelite Pressure Washer Pre-Cleaner
The pre-cleaner might be clogged. However, this is rare.
Highly Likely
