The steps in this guide will show you how to make a go-kart using a lawnmower's engine.
Steps
Step 1. Choose a go-kart chassis that can accommodate a vertical axis motor and transmission (you can choose the motor of a wheeled or pushed mower, while the transmission does not have to be 'transaxle')
Step 2. Weld a metal plate to the bottom of the frame to hold the engine block and transmission
Step 3. Mount the motor and transmission by securing them with appropriate bolts
Remember that the position of the engine is not as important as that of the transmission. Align it with the gear on the go-kart's rear axle.
Step 4. Change the drive pinion to a 16 tooth one
Step 5. You can use the mower's belt-driven manual clutch to connect the motor to the transmission, or purchase a go-kart centrifugal clutch
Just remember to maintain a 1: 1 ratio between engine and transmission.
Step 6. Connect the throttle cable to the carburetor lever that adjusts the opening of the fuel fill valve
Advice
- A simple go-kart should meet the needs of an average driver.
- Before you fill up with gasoline, or top up the oil levels, wait for the engine block to cool to avoid starting a fire or explosion.
- Before starting, measure the size of the motor, then choose a frame that can accommodate it adequately.
- Use your go-kart only in areas specially designed for this purpose or on your property. If you were to use it on public roads you would end up in trouble.
Warnings
- After removing the oil and grease residues with the gasoline, wait for it to evaporate completely to prevent the engine from catching fire.
- Handle gasoline carefully.
- Start welding only after wearing the clothing and tools for your safety.
