The Different Types of Carburetor for Generators

Generators are important to many industries, vehicles, and homes. And one of the most crucial components of a generator is its carburetor. Different types of carburetors are available depending on the type of generator and the application. 

In this blog post, we will share with you basics on generators, then discuss the different types of carburetor for generators and what makes each kind unique. Finally, we will provide some tips on how to choose the right carburetor for your generator.

Generator Basics

Generators are essential pieces of equipment with diverse applications. They are powered by a variety of fuels including gasoline, diesel, natural gas, propane, and solar energy. However, regardless of the fuel source, all generators require a carburetor to mix air and fuel and burn it efficiently. 

Most generators have an internal combustion engine, which consists of several parts that work together for the generator to run efficiently. The carburetor is one of the most vital components in this engine as it plays an essential role in generating power and ensuring the generator functions properly.

What is a Carburetor?

A carburetor is a device that regulates the air-fuel mixture entering the engine. It works by using different jets and passages to mix the fuel and air together before it makes its way into the engine. This process is called carburetion.

Carburetors are found in a variety of engines, including those found in automobiles, lawn mowers, generators, and other types of small engine applications. Without a carburetor, these engines would not start or run efficiently. Depending on your generator’s size and power output, you can choose from a range of carburetors to achieve the best performance from your generator.

Types of Carburetors

The most popular carburetor variety is the diaphragm type. This carburetor is often found on smaller engines, such as those in lawn mowers and snow blowers.

Another popular carburetor is the butterfly valve, which is also referred to as a slide or disc carburetor. This device is used on larger engines. The butterfly valve carburetor can be adjusted to provide the correct air-fuel mixture for any given engine size and performance level.

The third kind is the rotary disc, which is a more modern type of carburetor. This type of carburetor uses two discs that rotate to control the amount of air and fuel that goes into the engine. Rotary disc carburetors are typically found on higher-performance engines.

A different sort of carburetor is the mechanical or manual choke. This type is manually adjusted by a lever that regulates the amount of air and fuel mixture entering the engine. This type of carburetor can be used on both smaller and larger engines, but it is typically found on small engines.

The last carburetor is the electric choke. This variant is electronically controlled and adjusts air and fuel based on sensor readings from the engine’s computer. Electric chokes are usually found on modern vehicles and provide better fuel efficiency and emissions control than manual or mechanical chokes.

No matter what type of carburetor your generator has, it is important to properly maintain and service it regularly to ensure optimal performance.

Which Carburetor is Best for My Generator?

Choosing the right carburetor for your generator can be tricky. Depending on the size and power of your generator, certain types of carburetors may be better suited for your needs.

The most popular carburetors in generators are the Holley, the Mikuni, and the Dell’Orto. The Holley is a more traditional style of carburetor, while the Mikuni is a modern design that produces power extremely efficiently. The Dell’Orto is a slightly different design and is often preferred for larger generators.

When deciding which carburetor is best for you, there are a few factors to consider. You should take into account the fuel type your generator uses, the size and power of your generator, and the environment in which your generator will be used. For example, if you plan to use your generator in extreme temperatures or in a dusty area, then a carburetor with extra protection against these elements may be recommended.


A generator’s carburetor is responsible for mixing fuel and air and helping the engine run efficiently. There are several types of carburetors available for generators, each of which has its own set of benefits and drawbacks. In this blog post, we discussed the different types of carburetors available and provided an overview of their features.
