Kohler V-Twin Throttle Linkage(3 Quick Ways To Fix)

If you own a Kohler V-Twin engine, understanding its throttle linkage is crucial for optimal performance. The throttle linkage plays a vital role in controlling the engine’s speed and power output.

In this post, we will delve into the intricacies of Kohler V-Twin throttle linkage, its functions, common issues, and maintenance tips to keep your engine running smoothly.

Let’s jump in.

Understanding the Throttle Linkage

The throttle linkage in a Kohler V-Twin engine is responsible for connecting the throttle lever to the carburetor.

When you press or release the accelerator pedal, the linkage transfers this motion to the carburetor, allowing more or less air-fuel mixture to enter the engine cylinders.

This, in turn, regulates the engine’s RPM (Revolutions Per Minute) and controls its speed.

Components of Throttle Linkage

The throttle linkage system consists of several components:

Throttle Lever

The throttle lever is the user-operated component that controls the engine’s speed. When you press the gas pedal, the throttle lever opens, increasing the engine’s RPM, and vice versa.

Throttle Rod

The throttle rod connects the throttle lever to the throttle plate on the carburetor. It transfers the movement from the lever to the carburetor, controlling the flow of the air-fuel mixture.


The governor is a mechanical device that senses changes in engine load and adjusts the throttle to maintain a consistent engine speed under varying conditions.

1. Sticking Throttle

Over time, the throttle linkage can accumulate dirt and debris, leading to a sticking throttle. This issue can cause erratic engine behavior and may even lead to a dangerous situation if not addressed promptly.

2. Misalignment

Misalignment of the throttle linkage components can disrupt the smooth operation of the engine. It is essential to check for any misalignment and adjust the linkage accordingly.

3. Frayed or Damaged Throttle Cable

A frayed or damaged throttle cable can impede the movement of the throttle lever, affecting engine response and performance.

How often should I clean the throttle linkage?

Cleaning the throttle linkage once every six months is recommended. However, if you operate your engine in dusty or dirty environments, more frequent cleaning may be necessary.

Can I replace the throttle linkage myself?

While it’s possible to replace the throttle linkage yourself, it’s essential to have some mechanical knowledge and experience. If you’re unsure, it’s best to seek professional assistance.

Why is the engine speed fluctuating?

Fluctuating engine speed may be due to a malfunctioning throttle linkage, a misadjusted carburetor, or a dirty air filter. Proper inspection and maintenance can help identify the root cause.

How can I prevent throttle cable damage?

To prevent throttle cable damage, avoid applying excessive force on the gas pedal and ensure that the cable is free from any obstructions.

Can a damaged throttle linkage cause engine stalling?

Yes, a damaged throttle linkage can disrupt the engine’s air-fuel mixture, leading to stalling. Timely repairs are essential to avoid such issues.
