I do have a drive train from a Snapper 22hp. the engine has a BIG hole in it but I can get a different engine. A friend has an 18hp Briggs that I can have. I just don't want too much power to start out with.
I would like to build a go kart for my daughter. But how do I figure out what size engine to use? Mainly for use in the yard with a few hills. I have lots of old riding mower parts I could repurpose. Thanks.
