In gas-powered pressure or power washers, the carburetor is necessary to ensure the fuel is burning properly. The typical air to fuel ratio is between 12:1 and 15:1, and the carburetor keeps the balance where it needs to be for optimum performance levels from the equipment during use. Over time, the carburetor may clog, or the part will no longer function as it should. The signs of a failed carburetor include a poorly performing engine, smoke coming from the exhaust, overheating, backfiring, or difficulty starting the engine. In some cases, the part can be cleaned, while other times, the carburetor should be replaced.Remove the cover on the power washer with a screwdriver to replace a worn-out carburetor. Clamp the fuel line and note where the linkage is. Take off the air filter door. Remove the screws holding the carburetor. Replace with a new part and screw the carburetor back into position before removing clamps on the fuel line.This replacement carburetor is a genuine OEM part. It is sold as an individual piece.
