Cleaning and Maintaining Your Mower Carburetor

Your mower carburetor is responsible for helping start and run your lawn mower. If you don’t keep your carburetor clean your mower may run slow or not even run at all. To help avoid problems with your mower carburetor you should clean it and maintain it regularly. Every two to three months is how often you should check your carburetor. If it’s the beginning of the season or the end of the mowing season you’ll also want to check it before you let it sit over winter. This guide will help you clean and maintain your mower carburetor.

First you will need to take the carburetor off. To do this you’ll want to open the hood and remove the nut which holds the two parts of the carburetor together. Be sure not to lose the nut otherwise you will have difficulty getting the mower back together. Next you will want to pull the carburetor apart. It should come apart into two pieces allowing you to have full access to the inside of it.

Next you’ll want to focus on cleaning the inside of the carburetor. Search around the inside of the carburetor for gas. If you see liquid inside of it you will want to get a rag to clean it out. Next you will need to get special carburetor cleaner to clean the mower carburetor. If you use a cleaner that is not designed for carburetors you will run the risk of ruining the entire carburetor! While cleaning the carburetor you need to ensure that you clean out all of the debris and dirt that’s inside of it. This may take some time depending on how long it’s been since you last cleaned it. Also while you’re cleaning the inside of the carburetor you need to be careful as it’s made out of aluminum and therefore very easy to bend. Finally you can put the carburetor back together and put the nut on.

It’s important to know that you need to not only clean the carburetor but empty the gas tank before the end of the season. Many people don’t know that they should empty the gas tank and don’t understand why. The gas will cause the inside of the tank to start to rust over the winter. This will cause there to be many particles of rust in the gas. During the next season when you try to run the lawn mower you may find that the mower carburetor chokes out and dies because of the debris that was in the gas. Also when you leave gas sit too long it starts to turn into a varnish like substance. Therefore on top of the particles being in the gas you have the gas becoming varnish like which threatens your whole fuel system. Many mower users don’t realize that the mower carburetor can become clogged so easily. Remember that it is easier to care for and maintain your mower than it is to clean it and repair it later on.
