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.

Note:
The supplied product title mentions 5.5HP / 6.5HP / 212cc, but those terms usually refer to smaller GX160 / GX200 / Predator 212cc-style engines. This product’s dimensions and GX340 / GX390 positioning are more suitable for 11HP / 13HP-style engines. Please avoid using 212cc as a main fitment unless the original carburetor matches the same size and mounting layout.

Fitment FAQ
Will this part fit my specific model and year?
This carburetor is designed for select Honda GX340, GX390, 188F, 190F, and compatible clone engines used on generators, go-karts, mini bikes, water pumps, pressure washers, and other utility equipment. Please compare your original carburetor’s OEM number, intake diameter, mounting hole spacing, choke style, throttle linkage, fuel inlet position, gasket shape, and overall body design before ordering.
Do I need to match the OEM part number?
Yes, matching the OEM or reference number is strongly recommended. Common references for this application include 16100-ZE3-V01 and 16100-ZF6-V01. However, OEM number alone is not enough. Please also confirm the 30mm manifold intake diameter, 52.4mm air intake hole spacing, 27mm engine intake diameter, 52mm engine intake hole spacing, choke setup, throttle linkage, and gasket layout.
What models or situations does this part not fit?
This part does not fit GX160, GX200, Predator 212cc, 5.5HP, 6.5HP, or smaller 196cc / 212cc engines unless the original carburetor has the same size, bolt spacing, linkage, and air box setup. It also does not fit engines that use a different carburetor body, different choke design, different throttle linkage, fuel injection, or a different intake manifold. This part is not a replacement for the intake manifold, air filter, fuel tank, fuel line, governor linkage, or complete engine kit.
What should I check before ordering?
Before ordering, please check your engine model, horsepower, displacement, OEM/reference number, original carburetor style, manifold intake diameter, engine intake diameter, mounting hole spacing, throttle linkage, choke lever, fuel inlet position, gasket shape, and air box connection. For best fitment, compare the product photos and specifications with your original carburetor before purchase.
