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.

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.
