Glixal 20mm Performance CVK Carburetor for GY6 49–100cc — Electric Choke, Accelerator Pump

Glixal's ATMT1-073-1 is a 20mm performance CVK carburetor with an electric choke designed to replace PD18J/PD19J GY6 carburetors on 49–100cc Chinese scooters, ATVs, go-karts, and buggies.

This carburetor is a direct-replacement, higher-flow option for many Chinese-made small engines. It pairs a 20mm intake bore with an electric two-pin choke connector, an accelerator pump, and a built-in fuel filter to improve throttle response and simplify cold starts on compatible machines. The unit is supplied as a complete assembly for easy swap-in installation without extensive modification on most 139QMB, 139QMA and similar engine frames.

How does this carburetor improve performance and usability?

With a larger 20mm bore and included accelerator pump, this carburetor can deliver stronger fuel flow and crisper throttle response compared to smaller stock carbs. The electric choke helps with cold starts, while the integrated fuel filter reduces contaminants reaching the jet system.

• 20mm big-bore design increases airflow for improved throttle response
• Accelerator pump gives richer, instant response on throttle inputs
• Electric choke eases cold starts with a plug-and-play connector
• Built-in fuel filter protects internal passages from debris

What comes in the box, and what should I prepare for installation?

• Included: one 20mm Glixal big-bore CVK carburetor assembly
• Included extras: accelerator pump and fuel filter integrated into the unit
• Recommended prep: verify manifold gaskets, hose clamps, and matching electrical connector

Riders, mechanics, and DIY tuners who own Chinese-manufactured GY6-based scooters, small ATVs, go-karts, or buggies and need a straightforward, performance-focused replacement carburetor. If your vehicle uses PD18J/PD19J-type carburetors and your intake and filter mount dimensions match, this Glixal unit is a direct, higher-flow alternative that simplifies cold starting and sharpens throttle response without major modifications.
