AUTOKAY GY6 26mm Carburetor for 110-150cc Scooters Go-Karts — 43mm Airbox, Direct Replacement

The AUTOKAY GY6 150cc carburetor is a direct-replacement 26mm carburetor engineered for many 4-stroke 110–150cc scooters, mopeds and small go-karts.

This precision-cast carburetor supplies fuel and air to standard GY6-style 4-stroke engines and is sized to match a 26mm intake bore with a 43mm airbox outer diameter. Designed as a budget-friendly aftermarket swap, it offers the basic mechanical fittings and throttle linkage geometry needed to replace worn or damaged OEM carbs on a wide range of models. Before ordering, confirm your engine uses a GY6-style mount and check measurements against your existing carburetor.

Will this carburetor fit my scooter or go-kart model?

Compatibility centers on the GY6 4-stroke family and physical measurements. If your engine is 110cc, 125cc or 150cc and uses a GY6-style intake, this unit will likely bolt in with minimal modification. Always compare the intake inner diameter (26mm) and airbox outer diameter (43mm) to your current carb.

• Intake inner diameter: 26mm — matches many GY6 150 engines
• Airbox outer diameter: 43mm — verifies seal to air cleaner
• Mounting: designed for common GY6 4-stroke throttle and choke link points
• Recommended: measure your old carb and inspect throttle cable alignment

How do I install and tune the AUTOKAY GY6 carburetor?

Installation is straightforward for anyone familiar with small-engine swaps: remove the old carb, transfer any reusable fittings, and bolt the new carb in place. After mounting, fine-tune idle and mixture screws, and verify throttle response and choke operation before riding.

• Mounting: fit to intake manifold using existing gasket or new seal
• Linkage: align throttle and choke cables to prevent binding
• Initial tuning: set idle screw, then adjust air/fuel mixture for smooth idle
• Safety check: inspect for vacuum leaks and fuel drip before first start

What parts and measurements should I check before buying?

To prevent fitment issues, confirm three core details: intake bore size, airbox flange diameter, and throttle cable routing. Also compare fuel inlet style and any vacuum or vent hose locations so hoses and lines reach without stretching.

• Verify 26mm intake inner diameter against your manifold
• Confirm 43mm airbox outer diameter for proper air filter seating
• Check fuel inlet orientation and hose size compatibility
• Look for matching choke type (manual or automatic) and cable length

Will I need additional parts or modifications?

Many installations are plug-and-play, but some machines need small adjustments. Common extras include replacement gaskets, a new fuel line clamp, and occasionally a throttle cable or adapter to match the carb linkage. Keep a basic gasket set and hand tools on hand for a clean install.

• Recommended spares: intake gasket and fuel line clamps
• Possible upgrades: fresh throttle or choke cable to ensure smooth operation
• Tuning items: small flat screwdriver and tachometer for precise idle setting
• When to consult a mechanic: if manifold flange or vacuum ports differ from your stock parts

Who is this for? The AUTOKAY GY6 150cc 26mm carburetor is aimed at scooter and small go-kart owners, DIY mechanics, and repair shops seeking an affordable replacement for worn or damaged GY6-style 4-stroke carbs. It suits riders who can confirm measurements and perform basic installation and tuning, or anyone purchasing parts to prepare for professional fitting. If you need an exact match for a specialized or heavily modified engine, measure carefully or seek OEM specifications first.
