Pressure Washer: Smoke coming out of the engine exhaust

Smoke blows from the exhaust if the engine is overfilled with oil. Place the pressure washer on a level surface and check the oil level using the dipstick. If the engine is overfilled with oil, drain oil to within the proper range. An improper fuel/air mix can also cause the engine to smoke. Check the engine choke for the proper setting. A choke that won’t open causes excessive smoke. Check your carburetor system and rebuild or replace the carburetor if necessary.

These repairs may help solve your Pressure Washer problem:

Clean and rebuild the pressure washer carburetor

Carburetor rebuild kit

Rebuild kits are available for most carburetors. The kit contains essential components such as jets, pins, seals and gaskets for overhauling the carburetor. You can sometimes fix a fuel supply problem by disassembling, cleaning and rebuilding the carburetor.

Replace the pressure washer carburetor

Carburetor

Over time, varnish from stale gasoline builds up in the carburetor, decreasing the amount of air/fuel mixture reaching the engine. Replace the carburetor if it's severely clogged with varnish or if the orifices are clogged with debris and can't be cleared using carburetor cleaner and compressed air.
