I do believe you need a horizontal shaft engine. Your push mower uses a vertical shaft engine.

There are ways it can be done. Right angle gear boxes can be found to drive a solid axle, or a transaxle of some sort used...

Largely depends on what you want from it and how mechanical and creative you are or can become

Typically as Indy stated, horizontal shaft engines and a centrifugal clutch for a chain drive is used.

I built a go-kart for my grand-son using a horizontal shaft lawnmower engine and it would run just fine until we started riding in it,
Did some research and found that we needed a motor specificly designed for go-karts.
due to carburation and governor control issues caused from bumps and higher speed turns..

Good luck and have a great day

Without a right angle gearbox, a lawnmower engine is not a good fit for a kart. You will need a reliable clutch, Comet and others make good yet inexpensive systems, and make dang sure you have a reliable dead man throttle and kill switch.
We had a scooter made from plywood, wheel barrow wheels, bicycle forks and a Clinton tiller engine. No clutch so we had to push start it and didn't dare stall. Great fun until the police showed up and warned us to keep it off the road.
