Can I power a kart with this engine?
 

Hi,
I have this engine from my old lawn mower. I should note, I loved this mower, but the transmission for the self propulsion system was causing me problems, and I elected to spend a couple hundred more to simple buy the newer and better mower than parts to fix mine. The motor though, always first pull. Had it since new, and always did oil every year, new plug, and a carb kit when needed. Currently I just did everything, and the motor is perfect, but the trans took a poop. I want to keep something from the mower, and figured the motor would be fun in a cheap kart project with the little guy. Any suggestions?

If it's horizontal shaft then there are a lot of karts powered with similar engines. How many horse power is it?
