How do you build a Soapbox Car with a Lawn Mower Engine or similar engines?

To build a soapbox car using a lawn mower engine, start by designing a sturdy frame using wood or metal, ensuring it can support the engine's weight. Mount the lawn mower engine securely to the frame, connecting it to the rear axle with a chain or belt drive system for propulsion. Ensure the steering mechanism is functional, typically using a simple pivot system at the front wheels. Finally, don't forget to add safety features like a seatbelt and helmet for the driver.
