49cc 2-Stroke Carburettor – Integrated Fuel Tap, Manual Choke, Direct Fit
Is your engine struggling to start, or has your old carburettor started leaking fuel? Replacing it is a straightforward job that takes less than 30 minutes with the right part. This universal carburettor for 47cc, 49cc, and 50cc 2-stroke engines comes fully equipped with an integrated fuel tap and manual choke, ready for immediate installation on your pocket bike, mini ATV, or small scooter.
Note: Before ordering, please ensure the intake diameter is 13 mm and the distance between the mounting holes is 38 mm (centre-to-centre). These two measurements confirm direct compatibility with your engine flange.
Why choose this model? (Key Benefits):
- Integrated fuel tap — No need to buy extra parts; control your fuel flow directly from the carburettor body, reducing potential leak points.
- Manual choke included — Start your engine easily even after weeks in the garage or in cold weather, without excessive priming.
- 13 mm bore calibrated for 2-stroke — The air-fuel flow is precisely dimensioned for 47–50cc engines, ensuring optimal performance without running too rich or too lean.
- 38 mm mounting hole spacing (centre-to-centre) — Designed for a direct fit onto standard flanges, requiring no adapters or drilling.
- Wide compatibility — Suitable for most standard pocket bikes, mini ATVs, mini-motorcycles, and 2-stroke scooters in the 47–50cc range.
Details and Performance
Unlike carburettors without a fuel tap, this model allows you to shut off the fuel supply directly at the source — essential if you are storing your vehicle for a few days. The manual choke enriches the mixture for cold starts, reducing the number of attempts and saving your spark plug from fouling. The 13 mm diameter and 38 mm hole spacing follow the most common standards for small-displacement 2-stroke engines produced over the last 15 years, meaning installation is usually a simple, direct swap.

Frequently Asked Questions
How do I know if it is compatible with my 49cc engine?
Check two dimensions: the intake diameter of your current carburettor (it should be 13 mm) and the distance between the mounting bolts on the flange (it should be 38 mm, measured from the centre of one hole to the centre of the other). If both match, it is a direct fit.
Do I need a separate fuel tap?
No. The fuel tap is already built into the carburettor body. Simply connect your fuel line directly, and you are ready to go — no extra parts or additional connections required.
Will this work on a 4-stroke engine?
No. This carburettor is designed exclusively for 2-stroke engines. 4-stroke engines require a different version with specific jetting and float calibration.
What tools do I need for installation?
A screwdriver and a spanner are usually all you need. If the dimensions match, no modifications, drilling, or adapters are necessary.
