A go-kart carburetor is a mechanical component that is attached to the engine of a kart. The carburetor is responsible for mixing the correct air-to-fuel ratio, before the mixture goes into the combustion engine.

While carburetors are optional, they help to increase the performance of a go-kart, as the engine requires an optimal air/fuel ratio for maximum performance. In this review, we’ll be taking a look at the best carburetors for go-karts.

There is always a buying guide towards the end of this review that addresses some key aspects that should be taken into account before deciding to purchase one.

1. Fireshot VM22 Carburetor 

Specifications

• Mikuni clone
• Venturi Size: 26mm
• Comes with kit

The Fireshot VM22 Carburetor is the best carburetor for go-karts as it’s extremely high-quality for an affordable price. While it is a Mikuni clone, it delivers great performance for a very discounted price.

This go-kart carburetor is compatible with a variety of go-kart engines. One of its biggest features is that it’s highly adjustable and easy to install, as this carb kit comes with various components such as set and mounting screws, manifold and even an air filter!

One thing to note is that this carburetor comes with a relatively small main jet. Therefore, if you’re planning to optimize for performance, I recommend that you install a larger sized main and pilot jet.

Fireshot Carburetor Kit:

• 1 x Carburetor
• 1 x Air Filter
• 1 x Manifold
• 1 x Gasket
• 1 x Set Screws
• 1 x Mounting Screws

2. Mikuni 22mm Carburetor

The Mikuni 22mm Carburetor is a great premium option for go-karts. It’s made in Japan and all models sold in the United States and elsewhere are fully imported. It goes without saying that Japanese workmanship is generally impressive, and this also applies to this carb.

This is a round slide carburetor, which means that it’s going to have an efficient transition from idle speed, all the way to wide open throttle. You’ll experience a much smoother acceleration and power delivery with this carburetor.

Similar to the Fireshot carb, you’ll definitely need to install a larger main jet and pilot jet to take advantage of its performance capabilities. I recommend a pilot jet size of 140 for the main jet to really get the most out of this go-kart carburetor.

Take note that this carb also doesn’t come with any additional components or hardware, but this Mikuni Carburetor is definitely worth it for the performance it delivers.

Mikuni Carburetor Kit:

• 1 x Carburetor

3. Hooai Go-Kart Carburetor (PZ20)

The Hooai Carburetor is another great carburetor for go-karts, as it strikes a good balance between affordability, compatibility and build quality. The great thing about the PZ20 is that it comes in a set of 12 parts and contains all the items that you need.

This set even contains an air filter and the required fuel lines to ensure compatibility and a hassle-less setup. It will fit most types of go-karts, but you should always ensure to check the specifications and measurements.

Just take note of the intake diameter (20mm) and air filter diameter (32mm) if you choose to customize it with your own parts.

Hooai Carburetor Kit:

• 1 x Carburetor (PZ20)
• 1 x Fuel Line
• 2 x Fuel Filters
• 2 x Gaskets
• 2 x Intake Manifold Gaskets
• 2 x O-Rings
• 1 x 35mm Air Filter
• 1 x Air Filter Clamp

4. Auto Parts Go-Kart Carburetor (PZ22)

The Auto Parts Go-Kart Carburetor is another great set containing a carburetor, an air filter and the intake manifold. There are also certain accessories included such as clamps, meaning that you won’t have to source these parts individually.

If you want to upgrade certain parts, you’ll need to ensure that the measurements are compatible. The inner intake and air intake diameter are slightly larger than the standard go-kart carburetors, which is great for larger sized karts.

• 1 x Carburetor (PZ22)
• 2 x Intake Manifold
• 1 x Air Filter

5. QKPARTS Go-Kart Carburetor (PZ22)

The QKPARTS Go-Kart Carburetor comes with a 38mm air filter, inlet pipe manifold, two gaskets and an O-ring. These are all the parts you need to install this carb on your go-kart without having to source for any other parts.

This go-kart carburetor features a great build quality and can be easily assembled. It’s also relatively large in size (PZ22) and is therefore recommended for medium to large-sized go-karts.

6. DKII Game Go-Kart Carburetor (PZ19)

The DKII Game Go-Kart Carburetor (PZ19) is a carb that is designed for smaller go-karts. The great thing about this carburetor set is that it comes with quite an extensive kit. Besides a PZ19 carburetor you’ll get a fuel line, fuel filter, gaskets, intake manifold, air filter clamp and an air filter.

The air filter in this set is relatively small, as it’s designed for smaller go-karts. This means that if you’re looking for a larger one, you’ll need to replace it with a bigger air filter.

• 1 x Carburetor (PZ19)
• 1 x Fuel Line
• 1 x Fuel Filters
• 1 x Gaskets
• 1 x Intake Manifold Gaskets

7. FitBest Go-Kart Carburetor (PZ19)

The FitBest Go-Kart Carburetor is a great choice for people who want to replace their carb on their Harbor Freight Predator 6.5 HP 212cc engine. It’s a perfect fit and won’t require any type of adjustments or customizations.

Moreover, it’s a budget-friendly carburetor. However, you should take note that this carb only comes with basic parts. This means that you’ll need to look for fuel and air filters separately. If you do so, please take note of the specifications, to ensure a perfect fit.
