Today, we will be discussing how to clean carburetor on Toro lawn mower. 

The carburetor is a paramount component for every lawnmower. Its main function is to create a mixture of fuel and air in the right ratio. This mixture is so important for a lawn mower’s working that your lawn mower will not start properly. To understand its purpose, it is important to have an understanding of the working of an engine. 

The motion of a lawn mower is produced by heat energy, and the burning of fuel creates heat energy, and fuel needs air to burn. So the whole movement depends on the carburetor to create the combination of air and fuel in just the right ratio. Not only does the carburetor create this combination, but it also keeps it balanced for the proper working of a lawn mower. 

But what if your carburetor is failing? Your lawn mower will struggle to start or will not start at all. If you have a push lawn mower, the bad news for you is that you’ll have to go through the dilemma of pulling the starter rope again and again to start it. That could be a serious pain in the neck for you. 

The elephant in the room is that if you somehow succeed in starting your lawn mower, this joy won’t last long. There isn’t a snowball’s chance in hell that it will keep mowing your lawn seamlessly. Moreover, you’ll also notice that your lawn mower is taking more pulls to get started each time it dies. So you’ll be at your wit’s end trying to mow your lawn. 

But the problem is how to know if your carburetor is not in good working condition? The good thing here is that some symptoms will give you an indication that the carburetor needs your attention. Let’s discuss some of those symptoms. 

  • Hard starting is one of the most common symptoms of the damaged carburetor. If your carburetor is worn out or damaged, your lawn mower will not have a smooth start. If you have a lawn mower that starts with a key, it won’t start at all, plain and simple. But if you have a push lawn mower, it will take a few pulls to get started. And when it finally gets started, it will very likely just die soon. 
  • Another symptom that is associated with the poor carburetor is the black smoke coming out of the muffler. This black smoke results from your engine running rich and running rich means that there are more fuel and less air than required in the air to fuel ratio. In contrast, if there is more air and less fuel in air to fuel ratio, it is called running lean. Both abnormalities happen when the carburetor fails and harms your lawn mower. 
  • Overheating is another common symptom of a bad carburetor. A lean mixture could cause it. It may also lead to an engine backfiring in some cases. Besides overheating and backfiring, a lean mixture can also result in less engine efficiency. 
  • Apart from these aforementioned symptoms, you may also notice that your lawn mower is consuming more fuel than usual. So excessive fuel consumption is another symptom of a worn-out carburetor.

  • Follow these steps to clean your Toro lawn mower thoroughly. 
  • Please turn off your lawn mower and give it some time to cool down.
  • Once it has cooled down, remove the air filters and examine them. If you find any debris there, remove it. 
  • Take off the screw to release the bowl. Then clean it too. You can reinstall it after some time.
  • Inspect all other connections and make sure they are all free of any deposits and debris. Remove them for the proper functioning of your lawn mower.
  • Now start cleaning the carburetor. A carburetor cleaning spray is a good choice to clean it. Since you have the inside view now, all you need to do is spray the cleaner right into the carburettor’s centre. Make sure you have turned the engine on as it will make the cleaning process easier. It will eliminate all kinds of deposits which clogged the passage. 
  • Once you are done cleaning the carburetor. Restore its original shape and reinstall all components. That is the time to check that all components are doing good. See if it needs maintenance, such as replacing the air filters and many more.
  • Now start the engine and see if everything is going smooth.

As you can see, this was an easy process, and you can do it yourself. However, if maintaining equipment and components is not your thing, you can take your carburetor to a mechanic.
