How to clean a carburetor?
By Bardahl • The 11/30/2018 • 5 min reading
Before cleaning your carburetor, ensure that your 2-stroke mixture is not too rich in oil and that your fuel isn't from last year.
Over time, gasoline loses its characteristics. That's why Bardahl's fuel stabilizer often solves engine starting issues in the spring.
If your engine still won't start, we recommend using Bardahl's Engine Start.
If the engine doesn't start, it's necessary to visually inspect your spark plug and possibly scrub it with a small wire brush, as other elements besides the carburetor could be causing the engine problem on your garden tool.
If your carburetor is clogged and the engine won't start or doesn't idle properly, it’s time to clean it.
Where to start?
Start by cleaning the outside of the carburetor with our Bardahl Carburetor Cleaner. This is a powerful degreaser that can be used both inside and outside the carburetor.
Once dust and grass are removed, you can proceed in one of two ways, depending on your engine's configuration.
Either you perform a complete disassembly of the carburetor, or a partial disassembly. In the case of partial disassembly, simply remove the air filter to inject Bardahl Carburetor Cleaner directly into the air intake.
Try to start your engine and give it a few revs to eliminate deposits. If the engine does not start and other potential causes have been ruled out, a complete disassembly may be necessary.
In this case, unscrew all the linkages and block the fuel supply. Once the carburetor is fully detached from your lawnmower or garden tool, you can open the valve and spray the jet multiple times.
Let it dry and then reassemble the carburetor, linkages, and fuel supply.
You can now prime your carburetor and start your engine as usual.
