EZGO Throttle Linkage Adjustment: How to Troubleshoot & Fix

If you’re a proud owner of an EZGO golf cart like I am, then you know that smooth acceleration is key to a comfortable ride.

But what do you do when your throttle feels sluggish or unresponsive?

That’s where EZGO throttle linkage adjustment comes in, my friends!

I recently had to tweak my throttle linkage and let me tell you, it made a world of difference.

In this blog post, I’m going to share my personal experience with adjusting the throttle linkage on my EZGO golf cart, so that you can do it too and get back to enjoying a smooth ride.

EZGO Throttle Linkage Adjustment

Follow these steps for EZGO Throttle Linkage Adjustment:

  1. Find the throttle linkage that connects the accelerator pedal to the carburetor.
  2. Disconnect the battery before working on the throttle linkage to avoid electric shock or damage to the system.
  3. Locate the cable adjuster, usually near the carburetor and identified by a small round knob.
  4. Adjust the cable clockwise or counterclockwise to increase or decrease the throttle accordingly.
  5. After adjusting the cable, press the accelerator pedal to test the throttle. The golf cart should move forward smoothly and respond appropriately to the accelerator pedal.
  6. Repeat the cable adjustment and throttle testing process until the desired throttle response is achieved.
  7. After adjusting the throttle linkage, reconnect the battery to your golf cart.

How the Throttle Linkage System Works in An EZGO Golf Cart?

The EZGo golf cart’s throttle linkage system controls the amount of air-fuel mixture entering the engine. 

The accelerator pedal is connected to the carburetor via rod and linkage components. Pressing the gas pedal opens the carburetor’s throttle plate, allowing more air and fuel to flow into the engine. As this happens, the speed increases. 

The throttle linkage system also includes a governor that regulates the golf cart’s top speed by limiting the amount of air and fuel entering the engine, even when the accelerator pedal is fully pressed down.

Troubleshooting EZGO Throttle Linkage Problems and Fixes

Some problems can be experienced in your throttle linkage, which sometimes causes acceleration issues. This aspect of the article focuses on those problems and their fixes.


  • Dirty or clogged carburetor.
  • Loose or damaged cable.
  • Faulty throttle potentiometer.
  • Worn or broken throttle linkage components.


  1. Check the Carburetor, as it may need to be cleaned or rebuilt. Use a carburetor cleaning solution and follow the instructions carefully or call a professional mechanic if the carburetor needs to be rebuilt.
  2. Check the throttle cable to ensure it is correctly attached to the carburetor and throttle, and tighten the cable if it is loose and see if that solves the problem. Suppose it doesn’t; replace it.
  3. Check the throttle linkage for any loose or damaged parts. If any parts are damaged, replace them with new ones.
  4. Dirt and debris can collect on the throttle linkage and cause it to stick. Clean the throttle linkage and see if that fixes the problem.
  5. Adjust the Throttle Linkage if it is not properly aligned. Make sure you consult the owner’s manual for the correct procedures.
