Fun: Go-karts are a great way to have fun and get some exercise at the same time. They’re also a great way to teach your children or grandchildren how to work on engines and weld.

Affordable: Go-karts are relatively affordable compared to other types of vehicles. You can often find them for sale used or build them for a fraction of the cost of a car.

Portable: Go-karts are portable, which means they can be taken with you wherever you go. This makes them perfect for racing or cruising around town.

Customizable: Go-karts can be customized to your liking. You can add a roll cage for safety, put racing stickers on them, or even change the engine to go faster.

Steps for Building Lawn Mower Go-Kart

Step 1: Remove the Engine from the Lawn Mower

The first step is to remove the engine from the lawn mower. You’ll need to disconnect the spark plug wire, unscrew the bolts holding the engine in place, and lift the engine out. Once the engine is out, you can begin disassembling it.

Step 2: Disassemble the Engine

Now that the engine is out of the lawn mower, you’ll need to disassemble it. Begin by removing the carburetor, muffler, air filter, and other parts attached to the engine. Next, remove the flywheel and governor weights. Finally, unscrew the crankshaft from the engine block.

Step 3: Clean and Inspect all Parts

Once the parts are removed, it’s time to clean and inspect them. Use a brush and some degreaser to clean the dirt and grime off the elements. Inspect the details for any damage or wear and tear. If any parts are damaged, you’ll need to replace them before proceeding.

Step 4: Attach the Engine to the Go Kart Frame

Now it’s time to attach the engine to the go-kart frame. Begin by welding a bracket to the go-kart frame to support the engine. Next, bolt the engine to the rack using large washers and nuts. Make sure that the machine is securely attached before moving on.

Step 5: Install the Throttle Linkage

The next step is to install the throttle linkage. This will connect the throttle pedal to the carburetor so that you can control the speed of the go-kart. Begin by drilling a hole in the go-kart frame for the throttle cable to pass through. Next, attach the throttle cable to the carburetor and route it through the hole in the frame. Finally, attach the other end of the throttle cable to the throttle pedal.

Step 6: Install the Brakes

The last step is to install the brakes. If your go-kart doesn’t have brakes, it’s not safe to ride! Begin by attaching a brake lever to the go-kart frame. Next, run a brake cable from the lever to one of the wheels. Repeat this process for the other wheel. Finally, adjust the brakes so that they’re correctly aligned.


Go-karts are a great way to have fun and get some exercise. They’re also relatively affordable and customizable. If you’re considering getting a go-kart, take proper safety precautions while riding, and always wear a helmet!
