How to Fix a Lawn Mower Throttle Cable? (Solved!)

The throttle cable of the lawnmower is responsible for controlling the speed of the engine. It additionally regulates the fuel consumption of the engine when mowing. Failure of the throttle cable will actually cause trouble for the entire lawnmower.

If the lawnmower does not respond or the engine freezes when using the throttle, you need to check the cable.

In most modern lawn pushers, the throttle cable is connected to the intake valve of the carburetor.

When the throttle cable breaks, the intake valve will remain stationary and it will be difficult to start.

Over time, the cable will be stretched, worn, and eventually broken. After breakage, you will no longer be able to use the lawnmower.

In all cases, the cables need to be fixed or replaced.

However, do you encounter the same problem?

Then don’t worry. Repairing the throttle cable of a lawnmower is easy, but you need a perfect guide.

In this blog post, I will provide you with a perfect guide on how to fix the throttle cable of a lawnmower.

So without wasting any time, let’s fix it now.

A guide to repairing the throttle cable of a lawn mower

Basically, if you store the lawnmower for a long time or run the lawnmower at high speed, the throttle cable of the lawnmower will have problems. A few simple steps can help you fix the throttle line.

Before understanding the main facts, let us first understand the conditions required to repair the throttle cable of the lawnmower.

Tools Required:

  • A screwdriver
  • Tape measure
  • Socket wrench
  • Pliers

Now, follow the steps outlined below to obtain the proper solution.

Steps to Follow:

Step 1: Check the Throttle Lever

Push the throttle lever of the lawnmower back and forth to check whether the handle of the throttle lever moves the cable.

Step 2: Remove the Air Filter cover

Use a screwdriver to remove the air filter cover. This will help you check the throttle arm of the throttle.

Step 3: Measure the Distance

Now measure the distance between the throttle arm and the throttle lever. The distance should be 0-1 mm.

Step 4: Loosen the cable regulator nut

If the distance is greater, use a socket wrench to loosen the nut. Move the cable adjuster up or down to adjust the exact distance.

Step 5: Tighten the cable regulator nut

The loosened nut basically fixes the throttle cable. Use pliers to pull the throttle cable until it is tight.

Now, use a socket wrench to tighten the loosened nut.

The throttle cable sometimes gets stuck due to dust and rust. Because the throttle cable is stuck, it is difficult to control the speed of the lawnmower.

How to eliminate the stuck throttle cable.

Tools Required:

  • A screwdriver
  • Pliers
  • Socket wrench
  • Penetrating oil
  • Silicone lubricant
  • Funnel
  • Electrical tape
  • Paper towels or rags

Please follow the process described below to resolve this issue.

Steps to follow:

Step 1: Disconnect and observe the throttle cable

Disconnect the throttle cable on both ends out of your lawnmower. Observe the ends of the throttle cable carefully or take pictures to facilitate re-installation.

Step 2: Attach the Funnel

Now, loosen the bracket holding the throttle cable in the lawnmower engine. Put the engine end of the throttle cable in your hand, and then place the funnel at the cable port. Use electrical tape to connect the funnel to the cable port for sealing.

Step 3: Apply Penetrating Oil

Place the pan on the other side of the cable. Pour a sufficient amount of penetrating oil into the funnel. It will remove dirt and rust from the throttle cable. Wait until the penetrating oil is completely drained from the throttle cable.

Step 4: Adjust the inner line of the throttle

After draining the oil, use pliers to grasp the cable inside the throttle. Pull the cable up and down until the cable moves freely.

Step 5: Apply Silicone Lubricant

Now, spray some silicone lubricant inside the cable. When the cable is free, remove the funnel and re-install the cable to its original position.

That’s all. In this way, you can easily fix the throttle cable of the lawnmower.
