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???????????????????

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:

http://www.blmra.co.uk/
http://www.lawnmowerworld.co.uk/lawnmower%20racing.htm

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.

that is an awesome image - *man racing down road on a wooden seat with two chainsaws roaring away in the back and dozens of squirrels running for their lives* Might try that...

Hehe, sounds like the plan I have for a go kart, well it wont look or function like a go kart so much as a spaceship...

If you are using a vertical shaft engine you need a twisted-belt and pulley system to get the power to a horizontal axle. Use a dis-engageable tensioner w/pulley as a clutch. My son has a riding mower with that set-up and it'll do wheelies and burnouts, depending on how heavy the driver is!

Yeah. If you have a pulley on your engines shaft, and a pulley on your drive-wheel/axle, put a belt slightly too large on there. Then make/buy a tensioner with a pulley on it to take up the slack to make the belt tight. Rig a cable or lever to that tensioner so that you can engage/dis-engage it at will. It will work like a clutch. You might have to fabricate some sort of belt-guide to keep the belt from falling off when you take the tension off.

I've built one before.... actually... twice. You're going to need a frame, some wheels, etc. etc. I can't list all the parts, 'cause there's just too many, but Nacho seems to have the right idea. I haven't made one with shocks yet, but plan to do so in the future. Some kids in my school actually found a site where you can buy a full go-kart kit, including the engine. I think it was around $500, but I'm not sure.

you'd need a bevel gear because the lawn moro engine has to work straight up.

Belt driven, chain driven, or do you need a transmission ? *sigh*
