Carburetor Assembly
The GC160 uses extremely fine metering orifices in the main jet and emulsion tube that are prone to varnish and ethanol-related corrosion. When these passages are partially restricted, the engine will start on the initial prime/choke circuit but fail to transition to the main circuit once the choke is opened or a load is applied. Replacing the assembly ensures all internal passages, which are difficult to clean manually, are clear.

Gas Tank Cap (Vented)
A faulty or clogged vent in the fuel cap prevents air from entering the tank as fuel is consumed, creating a vacuum that overcomes the gravity-fed fuel system. This causes the engine to run for several minutes until the fuel flow is completely choked off. Replacing the cap restores the atmospheric pressure balance required for consistent fuel delivery.

Pump Unloader Valve Kit
If the engine dies specifically when the operator releases the spray gun trigger, the unloader valve is likely seized or corroded. This prevents the pump from entering bypass mode, causing an immediate high-pressure spike that exceeds the engine's torque capacity at idle. Cleaning or replacing the unloader restores the bypass circuit and prevents stalling under no-load conditions.
