Carburetor for Honda GX340 GX390 188F 11HP 13HP Generator Go Kart Engine

Product Overview

Replace a worn, clogged, leaking, or poorly performing carburetor with this replacement carburetor, designed for select Honda GX340, GX390, 188F, 190F, and compatible clone engines used on generators, water pumps, pressure washers, mini bikes, go-karts, construction equipment, and other small-engine applications.

The carburetor controls the air and fuel mixture entering the engine. A properly working carburetor can help improve starting, idle stability, throttle response, fuel delivery, acceleration, and overall engine performance. If your GX340 / GX390-style engine has hard starting, rough idle, fuel overflow, hesitation, poor acceleration, unstable running, or poor fuel economy, replacing the carburetor may help restore smoother operation.

This carburetor features a 30mm manifold intake diameter, 52.4mm air intake hole spacing, 27mm engine intake diameter, and 52mm engine intake hole spacing. Please compare your original carburetor’s OEM number, intake size, bolt spacing, choke style, throttle linkage, fuel inlet position, gasket shape, and overall body design before ordering.
