We bought the cheapest diesel engine available on eBay (however the engine was still very expensive). We’ve been wanting to build a diesel go kart for years, and we finally bit the bullet on the cheap small diesel engine. This diesel engine is 411cc, 10HP, and around 20 foot pounds of torque. It’s heavy too! Today, we’re installing the diesel engine on a cheap go kart to see if it will run and do wheelies. The result is not disappointing!
