There is an issue with lawnmower engines - Most are 4 stroke machines that have been designed to run fairly slowly this is difficult to over come. you will need to devise a clutch and possible a gear box to be useful. Also adequate brakes.

I used a rally plus riding mower with a Briggs and Stratton 18 HP engine. I also published an instructable on how to build a go kart with a horizontal shaft engine.

Smasher 555 is right. Me and a couple of friends were goign to try to make a go kart out of a lawnmower engine, but then you would need some kind of customized differential and that would take too much work, and would also significantly reduce your gear ratio. It would cost less and be much more efficient to buy a horizontal shaft engine.

First you need a horizontal shaft engine. Mount it to a frame with a centripatel clutch on the rear axle with a chain and sprocket on the engine shaft.
Have you tried This?

either hydraulics or a riding mower transmission and step up the drive ratio.
