I need help figuring out a setup, I have a 20hp riding mower engine to which I would like to mount on a go kart but I don't have gearbox so is there a way I can mount some idler pulleys in the frame of the go kart and run a belt to a centrifugal clutch or to a torque converter thus making it work???????????????????

I'm building a cart with a challenge xtreme 3.5hp four stroke engine , is there any way of getting more power from it ??? And also what's the best thing to do for my stearing system ??? Help would be much ablidged
If this was to become an instructable, then there would be quite the number of possibilities for what could be done with a lawn mower engine, or even a gas powered weed whacker! id like to see that put to good use!

Why not just add a seat to the lawnmower, or to a trailer behind the lawnmower? Lawnmower racing is a recognised sport in the UK. You could compete in a Class 2 race:

From http://www.trymysport.co.uk/lawn_mower_racing.htm :

As a general rule, there are 4 classes of Racing Lawn Mower: ~

Class 1 – These are walk (or rather run) behind Lawn Mowers and these can travel as fast as whoever is pushing them along!
Class 2 – Roller driven Lawn Mowers with a towed seat. Typically these Lawn Mowers would cut Cricket Pitches and Bowling Greens and are capable of about 35mph
Class 3 – Small Garden Lawn Mowers powered by a 10hp Lawn Mower engine. These are capable of speeds in excess of 50mph and are currently the favoured Class by most competitors
Class 4 – This is a new Class for small Bonneted Tractors, and as such these tend to be slightly larger in size than the Class 3 Lawn Mowers. However, they are the future of the sport and have potential top speeds of over 50mph

Oh, and trust the Yanks to get in on the idea: http://www.letsmow.com/
I have an old Yamaha XS 1100. It looks like aweful, but still runs well. My kids wanted to put the engine on one of my old mowers. Is there a class for that?
Kiteman, I hope to see you at the championships... Your scouts could be a handy source of light and expendable racing drivers, not to mention being able to tie it together if there's a crash...

. It will probably be easier to engineer if you will use a horizontal shaft engine. (When I think "lawnmower engine," I see a vertical shaft engine on a walk-behind mower.) Chainsaw engines work better than you might suspect from their small size. . You will need a centrifugal bell clutch w/gear (an old chainsaw engine should have one attached), chain (bicycle chain will work, but probably won't hold up for long - get some small motorcycle chain), and a sprocket for the axle. . If you don't plan on turning much, a solid axle will work (most go-carts don't have a lot of traction in the rear), but I don't recommend it.
