Lawn Mower Carburetor
The carburetor is one of the essential parts of your lawn mower’s engine. It ensures that the right mixture of fuel and air goes into the cylinder so that combustion can occur. Spark plugs ignite the fuel and air mixtures, which burn and push the engine piston down, which, in turn, rotates the crankshaft, which is what makes the lawnmower blade turn. The wheels will also begin to rotate depending on the type of lawnmower you have (such as a riding mower or a self-propelled mower).
Where can you find and identify the carburetor on a lawn mower?
The carburetor is part of an engine in a lawnmower. It is usually mounted on the side or top of the engine, connected to the gas tank, and usually located just below the air filter. In most cases, homeowners can replace their lawn mower’s air filter as part of a routine annual maintenance procedure by quickly accessing and identifying the air filter housing.
The carburetor is the next part of your mower’s engine, right behind the air filter. Despite the differences in location, there are some characteristics that most carbs share to make identification easier. Metal carburetors are rectangular. Your mower’s carb has black areas on the right and left, like a black circle.
Types of Lawnmower
We will go over the types of lawnmowers in this section and usually find the carburetor. There are two main types of lawnmowers:
1. Walk-behind lawnmowers
There are four basic types of walk-behind mowers, which is the list below – if you have a walk-behind mower, make sure you know which type it is so you can refer to the appropriate part of this article to locate its carburetor:
- Electric walk-behind mower
- Self-propelled lawnmower
- Mower with two functions
- Mower with three functions
2. The riding lawnmower
Below are three different types of riding lawnmowers. If you have a riding lawn mower, make sure you know which type it is so that you can locate the carburetor according to where it is located:
- Rear engine riding lawn mowers
- The lawn tractors
- Zero-turn mowers
Where is the carburetor on walk-behind lawnmowers?
As we will discuss later, the carburetor is connected to a walk-behind mower’s air intake and air filter. You can usually find the carburetor on the side of the mower, above the base. The carburetor is therefore easy to locate when these components are found. The carburetor of a lawnmower is located behind the black plastic housing for the mower’s air filter. Remove the housing and air filter (usually two bolts behind the filter).
You’ll usually find them on the side of the mower’s engine, but they are sometimes on the top as well. If you can’t find them, look for the square-shaped or round-shaped filter housing. Most air filters have plastic cases that open quickly to allow easy maintenance. In most mowers, the carburetor is located just behind the air filter’s housing, and there are usually 2-3 bolts that need to be loosened to remove the housing.
Where is the carburetor on the riding lawnmowers?
On a riding mower, the carburetor is usually found on the side of the engine. The carb is located below or behind the air filter on a walk-behind mower. To reach the carb, you must remove the filter and the air filter housing. By following the fuel line from the gas tank to the carburetor, you can identify the carburetor once the air filter housing is removed.
The process for replacing or repairing a carburetor in a riding mower depends on your exact model. This is usually more complicated than working with a carburetor on a walk-behind mower, so you may want to hire a professional at a small engine repair center to do this for you. It would help if you referred to your machine’s manual when doing carb repair or replacement so that you can remember how the carb was set up and have an easier time attaching everything again.
Steps for finding where a carburetor is on a lawnmower?
Although each lawn mower is different, following the steps below should help you locate the carburetor in your mower’s engine.
Turn off your mower’s ignition and use the parking brake to prevent accidental rolling. Gear the mower to prevent it from rolling.
Releasing any hood latches or restraining devices holding down the hood will allow access to the mower’s engine.
You will generally find the air intake and the filter on the engine’s side or at the top. The air intake should have a square or round housing with a slit or hole in the top. The carburetor should be fastened to this housing with screws or latches. Filters are located within the housing so that dust and dirt will not get into your mower’s carburetor because the housing contains foam or paper filters.
Observe the fuel line that leads to the gas tank. You can use this information to find the location of the gas tank. Gas tanks are usually located conveniently for refueling and are often black.
There are usually clamps on the fuel line that attaches to the tank. You can trace the fuel line from the tank to the carburetor. Find the fuel line that comes from the tank. Usually, this will be close to the bottom of the tank. Find the fuel line that connects the carburetor to the tank.
FAQs (Frequently Asked Questions)
- When the lawnmower starts, does it not stay running?
Filling the gas tank and oil reservoir are the first steps you should take when checking why your lawn mower won’t run, but you should also check for a dirty filter, a clogged carburetor, an improper fuel mixture, and even a dirty spark plug. To get back to trimming your grass, you may need to hire a lawnmower specialist.
- How to fix the lawnmower not getting gas?
The fuel filter can clog, or the carburetor inlet needle can get stuck. Remove the fuel line at the carburetor to determine if there is a clogged fuel filter or a kinked fuel line. If you still don’t get gas, see any debris inside the tank that could clog the fuel outlet.
- Where is the carburetor on a lawnmower?
Carburetors are part of the mower’s engine, typically located on the side or top of the engine. They are also connected to the gas tank and are often located below or behind the air filter.
