Go Kart Acceleration Problems You Need To Notice

Driving a Go-kart can be fun, but there are problems you need to be aware of as well when driving this interesting vehicle. As a kart owner and driver, you need to fully detect the acceleration problems that keep your engine not working properly as they used to be.

Our article today will show you all Go Kart acceleration problems that can possibly endanger your kart. Check them out now to be a considerate owner of your kart!

Go Kart Acceleration Problems

Here are some of the most problematic incidents that can happen to your kart. We will look through what they are and how to fix them.

Problem 1: Go-kart Engine Will Not Run 

Go Kart Acceleration Problems

One of the most frequently seen problems in a go-kart is that they don’t start. It is considered a major problem since without a kart starting properly, you cannot ride it nor do anything with it. 

However, you can be relieved, as the solutions to this complicated problem are easy to detect. 

But first, let’s discover why your go-kart doesn’t start in the first place. The main causes can be referred back to the electric or fuel issues, specifically one in these issues:

  • Broken spark plug
  • Not enough fuel for the machine
  • Engaged kill switch
  • There is too much choke in the engine
  • Broken hose or fuel line

No matter what the causes are, here are the solutions you can have a look at to troubleshoot this problem:

A Full Check On Fuel and Power

The first thing to check when troubleshooting a go-kart with an engine that will not start is to check that you have enough fuel and power for the go-kart. It may seem like it should not need to be said, but you should always check to make sure there is enough gas for the vehicle.

When troubleshooting a kart that doesn’t start, we must look at its fuel and power level first. Although it may be a redundant thing to say, you should always check if your kart has enough gas or not before concluding that you cannot start the kart. 

Sometimes people forget to put in more gas for their karts, which will lead to no-starting karts. Sounds as funny as it is; this situation can happen to any kart rider. 

If your kart has a low gas level or no gas, remember to fill it with gas. If the problem is low or no gas level in the first place, giving your kart some fuel will fix the problem right away without any further conditions.

And also, a charger battery is required. Once you are sure there is a full charge on the kart, it is good to go.

Ensure Fuel Reaches Carburetor 

Once you are sure about the sufficient gas amount poured into the fuel tank, it still won’t work if there is another problem causing the engine not to start, specifically something that keeps the fuel from reaching the carburetor. 

To check if your carburetor is receiving fuel or not, check out these steps below:

  • Get a tank of starting fluid on hand
  • Spray a bit of starting fluid directly into the carburetor
  • Attempt starting the engine

With the starting fluid inside the carburetor, the engine should have started by now. If the go-kart’s engine starts at that time but is no longer running when the starting fluid has run out, now you can detect the problem: the carburetor cannot get fuel. 

You should make a replacement to the lines if the damage starts from the gas hose. 

Problem 2: Go-Kart Idling Incorrectly

There may be troubles starting the go-kart and keeping the engine going smoothly. Compared to the starting troubles, the idling problem can be more difficult to detect but easier to solve in the end. 

So, what are the reasons for an idling engine? The main reason many drivers have indicated in the past is a clogged air filter. 

When water gets into the tank and mixes with the original gasoline, it can cause the engine to start but stop sooner rather than idling. One sign to detect if water has reached the tank is that water becomes beading at the tank’s bottom. 

The proper solution to this problem is empty the tank wholly by following these steps:

  • Remove all gasoline from the carburetor and the fuel tank. 
  • Pour in the new gasoline once the fuel has been drained.
  • If there is a cap or tank leak, you must take a test beforehand. 

You can alternate gasoline with water to test the fuel tank to see if there is any leak in the tank or the cap. If there is a leak, it should be handled properly before gasoline.

Problem 3: Go-kart Braking and Accelerating Abnormally

Go-kart Braking and Accelerating Abnormally

The last common problem with the go-kart we list today is the struggle to handle the brakes or acceleration. After using the kart for a long time, these issues can happen. 

One of the most critical components in a go-kart is the brake, which is why every kart driver should take care of the brakes carefully when driving this vehicle. 

For your safety, the brake should be responsive to help you deal with slowing down or speeding up when needed. The brake can degrade from time to time, so ensure you take care of the brake’s health well. 

The brake issues can be:

  • Not responsive in slowing down 
  • Not responsive in applying the brakes
  •  There is noise or grinding feeling when using the brake.

And here are our solutions to fix the brake:

Replace the Brake Pads

If you sense the grinding feel or sound when applying the brake, that is a strong sign you should replace your pads immediately. The new pads should be thick enough for qualified braking performances. 

You are in danger if you don’t replace your brake pads in time. Hence, it will cause the whole brake system to fall apart.

Check Brake Fluid Levels

Your brake can suffer from hydraulic brake fluid. Once you successfully indicate this reason, you can change the brake fluid levels to solve the problem.


Why Does My Go-Kart Bog Down When I Accelerate?

A closed choke is one critical reason your go-kart bog down while accelerating. When we start the engine, it’s common to close the choke, but drivers may forget to open it. Hence, the engine will suffer from improper combustion, and eventually, the whole system shuts down. 

How Do I Increase My Go-Kart Acceleration?

There are various ways to increase your go-kart’s accelerating performance. Here are some of the methods you can try with your vehicle. All methods include steps to follow, so make sure you select a profitable one for your kart, and everything will be fine!

The methods are:

  1. Change to a better Go-Kart
  2. Get a Supercharger or Turbocharger
  3. Optimize Your Carburetor
  4. Get rid of the Speed Governor
  5. Re-gear Your Go-Kart
  6. Make Your Go-Kart Lighter
  7. Include Isopropyl Alcohol in the system
  8. Switch to bigger tires
  9. Install a NOS Kit

How Do I Adjust My Go-Kart Throttle?

There are three-step on how to adjust the go-kart throttle:

Step 1: Slacken a clamp nut or bolt that tightens the governor level to the crank with a metric wrench.

Step 2: Revolve the throttle plate clockwise until you can’t do it anymore. Keep the plate in this position with one hand. 

Step 3: Put a metric driver onto the shaft where you detect a loosened nut. Rotate the nut driver in a counterclockwise direction to turn the shaft to the final position. Use a wrench to secure the nut or bolt.

How Do You Adjust A Go-Kart Carburetor?

You can adjust a go-kart carburetor; you can turn the screw on the carburetor close to the choke. To increase the idle speed, turn the screw clockwise and vice versa.

Why Does My Go-Kart Take Off So Slowly?

Your go-kart can start slow because of the damaged carburetor. A clogging problem may make the kart run more slowly than usual. 

Hence, it’s best to check if the carb has an optimized performance or not by looking at the carburetor. The main part mixes air with proper ratio before flowing into the engine.

What Is The Best Sprocket Ratio For A Go-Kart?

The best sprocket ratio for a go-kart is 6:1. Although it sounds not too optimal, it will ensure that the go-kart can go full speed on any road.

When racing in long straight tracks, it’s better to go for a lower gear ratio, such as 4:1 or 5:1. Bear in mind that this setting only applies for racing karts. The ratio number would be higher in rental or offroad karts, so you wouldn’t have to worry about that. 

The explanation for this ratio is that the lower the gear ratio, the higher the chance your kart’s clutch and the engine will wear out. It means that if your kart is running on a 1:1 ratio, there is a high possibility that it will die after a few track runs.

On the other hand, the greatest gear ratio for acceleration is higher, such as 7:1 or 8:1. There is no absolute value when it comes to the kart ratio, so it entirely depends on what kind of kart you are using. 

As every track is different, there won’t be any absolute similarities between the two gear ratios performing on each track. It’s critical to consult other drivers or track owners first to understand what their settings are. 

And most importantly, get the kart with a suitable kart ratio to ensure your kart runs smoothly to your driving habit.

What Does Removing The Governor Do?

One big plus point of removing the governor is raising the engine’s maximum rpm capacity. 

However, Predator 212, designated for 3600 rpm, won’t be a problem when it comes to governor removal, as the internal parts can frequently endure up to 5000 rpm without falling apart unless you decide to go for full throttle.


And that’s everything we have on the topic of frequently seen Go Kart acceleration problems that can happen to your endearing kart one day! It’s important to have these instructions in mind so that when your kart is unluckily suffering from these situations, you can handle them easily.
