The first step to usecarburetor cleaneron your mower is to remove the air filter housing. Remove the spark plug wire to safely work on the mower. Consult your mower manual for specific instructions and warnings.

Often the air cleaner housing must be removed using one of the following different tools:

  • screwdriver
  • Dirigent-Torx

In addition, some housings simply clip onto the mower. This means you can simply unclip and remove the case instead of having to loosen the mounting screws.

2. Remove the air filter from the housing

With the housing removed you will need to pull the air filter out of the mower. To do this, simply lever the air filter out of the housing with your fingers.

Some mowers are designed so that you can open the deck and leave the door open, and you can just remove the air filter with the door.

  • Agua
  • debris
  • Anything extraordinary

If the camera shows anything abnormal, be sure to clean the camera completely before proceeding to the next step.

There are two places on a lawnmower where you can spray carburetor cleaner. However, you must be careful when using carburetor cleaner as it is a highly flammable material.

To spray your carburetor cleaner on the lawnmower you can spray:

  • Right at the port of entry– This connection is located directly under the air filter. Once the air filter is removed, you can spray carburetor cleaner directly into the chamber.
  • In the spark plug connection– To locate this connector, refer to your mower manual. The location varies by machine.

Once you locate the intake port or spark plug port, all you have to do is spray the carburetor cleaner on for two to three seconds.A little carb cleanser goes a long way!

If using starting fluid, spray the fluid onto a rag and hold it against the intake port. Do not spray directly into the inlet opening.

Too much carburetor cleaner in the intake port or spark plug port can cause further engine damage. You don't need a lot of carburetor cleaner to get your mower running again.

  • Set the choke to the maximum position, sometimes referred to as the closed choke
  • Squeeze the primer plunger several times if you have one.

Your mower should start immediately. If that's the case, turn it off and replace the air filter and put the filter housing back on. Now you are ready to move!

If the problem persists in the future, you can always repeat the process, but it may also be worth having the machine checked by a professional. If you find yourself having to use a carburetor cleaner every time you start your mower, take it to a professional so you don't accidentally do more damage.

If the mower does not start after a few tugs or turns of the ignition key, you can repeat steps one through four. If the process still doesn't end with starting your mower, it's time to call a professional.
