Universal 26mm CVK Carburetor - GY6 150-181cc Big Bore
Description
This Universal Parts 26mm CVK Carburetor (SKU 164-323, MPN PD26) restores crisp throttle response, stable idling, and clean fuel delivery on GY6-powered scooters, buggies, and go-karts.
It is a direct OEM replacement on premium Taiwanese platforms that came with a 26mm carburetor, and a drop-in upgrade over a stock 24mm unit for anyone running a big-bore configuration that needs more fuel. It arrives pre-jetted with a #105 main and #35 pilot, a 2-pin electric choke already fitted, and an inline fuel filter in the box.
Key Features
- 26mm venturi bore: Increases air velocity and fuel atomization, clearing up mid-range flat spots.
- Electric choke fitted: Pre-installed 2-pin automatic choke handles cold-start enrichment in any weather.
- Adjustable enrichment screw: Accessible mixture circuit for quick tuning at different elevations.
- Pre-configured jetting: #105 main jet and #35 idle/pilot jet installed for out-of-the-box running.
- Inline fuel filter included: Keeps the fuel circuits clean from first start.

Compatibility
| Engine Architecture | Application |
|---|---|
| GY6 4-stroke 152QMI / 152QMJ, 125cc-150cc | Performance upgrade over the stock 24mm carb for standard platforms and off-road builds needing more fuel delivery |
| GY6 4-stroke 157QMI / 157QMJ, 150cc-170cc | Direct OEM replacement for premium Taiwanese scooters, utility buggies, and sport go-karts with a stock 26mm setup, and suits big-bore builds |
Check the engine code stamped on your machine before ordering. The intake side is 26mm I.D. with a 32mm O.D. and the air filter side is 38mm I.D. with a 43mm O.D., so cross-reference your intake manifold boot and air filter dimensions against those figures before buying.
Installation Notes
Before mounting, inspect the rubber intake manifold boot for cracks or dry rot, because even a small air leak causes a lean condition that will throw off your tuning. After installation, let the engine warm up fully for 5 to 10 minutes so the electric choke closes completely before you adjust idle speed or the enrichment screw.
This product is intended for off-road use only. This product is not intended for use on public roads or land.
