Carburetor Assembly
The float needle valve inside the carburetor often fails to seal due to debris or ethanol degradation, causing fuel to overflow into the throat and air box. On GC190 engines, replacing the entire assembly is the most reliable fix to ensure the internal venturi and jets are also free of the contamination that likely caused the needle failure.

Fuel Line
Standard rubber fuel lines on pressure washers are subject to high vibration and UV exposure, leading to dry-rot and cracking. A leak appearing to come from the 'engine' is frequently a cracked line at the carburetor inlet barb or the fuel tank outlet.

Carburetor Bowl Gasket
The O-ring seal between the carburetor body and the fuel bowl can shrink or flatten over time. This leads to a constant drip from the bottom of the carburetor even when the engine is not running, as it is the lowest point in the gravity-fed fuel system.
