Things required

These things are necessarily required in order to perform this operation safely.

  • Flathead or wing nut screwdriver 
  • Goggles
  • Rubber gloves

Step 1:- Detach the air filter

First, you have to remove the air filter from the mower. Use the flathead screwdriver to screw off the screws that hold the air cleaner. Take out the air filter from the air cleaning chamber.

Remember to store the screws and filter safely as you would need them to install back to the lawn mower.

Some engine models of Briggs and Stratton use the wing nut instead of the flathead to fix the air cleaners in the lawn mower.

Step 2:- Find the choke lever

The choke arm or lever needs to be located in the engine. It is a small bent plastic arm that controls the throttle’s adjustment on the handle of the lawn mower. It closes and opens the throttle with the help of a spring that is attached to the arm.

In some models of the engine, the choke lever is found in the speed control in the remote engine.

Step 3:- Adjust throttle to fast setting

Set the lever of the throttle towards the high or fast speed position. The mounting bracket, which holds the cable, is set with screws inside. Untwist the screws with the flat head screwdriver to make them loose to adjust the throttle cable easily to the support. 

Remember! Do not unscrew the screws completely.

Step 4:- Adjust the throttle cable 

Now, adjust and position the throttle cable in the last point of the closed space. Once you have fixed it, tighten the screws of the bracket mounting to secure the new adjustments.

Step 5:- Try out the throttle cable

Let’s have a test drive. Twist the throttle lever to the slow speed. Now twist the lever again towards the fast or high speed to test the adjusted controls of the lawn mower’s engine.

If it is performing by turning ON and OFF according to your commanded need and speed, then congratulations. You have done the adjustments successfully.

Step 6:- Assemble the air filter

It’s time to close the deal. Install the air filter that was removed in the first step. Screw it tightly to fit it back to its position.

Examine the air filter before installing it back. Clean it if it is just dusty or replace it according to its condition.
