FAQ#1: What is the best way to clean a carburetor?

There are a few ways to clean a carburetor. For starters, you can go to the store and pick up a cleaning kit of some sort. You can also try a homemade concoction if you'd like. Remember, whether you decide to use the store bought method or the homemade one, we want to warn you to be careful with the carburetor!

FAQ#2: What is the safest way to clean a carburetor?

When wanting to clean a carburetor, we advise you to use caution to avoid damaging said carburetor. When we started cleaning small engines like this, we used a simple yet effective method of gasoline and a brush. However, changed over to mineral spirits as well as a brush. In fact, this ties in nicely with our next bit of info.

Did you know that Walbro, a carburetor manufacturer, highly recommends their customers to use the mineral spirits and brush method? After all, who would know about cleaning a carburetor better than the carburetor manufacturer themselves?

Ultrasonic Cleaning your Chainsaw Carburetor

Mineral spirits can be purchased at any hardware store. In fact, our growing business is changing the way we clean carburetors, so that it is both effective and efficient. Recently, we have made an investment towards an ultrasonic machine; this has been by far the best and most economical method for us. Currently, we are using an Omeagaclean solution made by omegasonics This specific design is used to clean carburetors; it contains buffers to protect aluminum. Oh, and did we mention its eco-friendly? No worries there!

How to Clean a Chainsaw Carburetor Without Removing It

Now, lets assume your chainsaw’s carburetor hasn’t been cleaned in a long time. The best method to clean it is to take it apart and open it. Lets not risk having to take it parts twice so using a brush and cleaning solvent, thoroughly clean it. However, if you clean the carburetor regularly and know that the gum accumulation isn’t a major issue, you may clean it without the hassle of disassembling it. A carburetor cleaning liquid is required to clean a carburetor without removing or opening it. The following is the cleaning procedure:

Step 1

First, mix some carburetor cleaning solution into the gasoline of your chainsaw’s fuel tank. I suggest mixing 4 ounces of B12 carburetor cleaner into a tank of gas. Using a funnel, carefully pour the carburetor cleaning into the fuel tank.

Step 2

Start the chainsaw after combining the carburetor cleaner with the gas. Allow the chainsaw to run at low RPMs/idle for a few minutes. This allows the cleaner to pass through the carburetor, fuel systems, and idle engine.

The cleaner will wash away the sticky residue clogging the components, resulting in a clear path for the air and fuel. Turn down the idle dial when the RPMs begin to rise.

Step 3

If you want to properly clean your chainsaw’s carburetor, spray some B12 in the pilot air jet. It is normally kept from view so check your chainsaw’s owner’s handbook to determine where the carburetor’s pilot air jet is located.

Step 4

To make sure the cleaner did its job run chainsaw at full throttle if it starts effortlessly and continues to operate at high speed with no signs of speed or power decrease (bogging) your carburetor is cleaned.
