Thanks to others modern disposable living, I now have a surplus of ex-mower briggs and stratton engines ;D, was thinking I could build a dirty water pump pretty easily, but what else could I use them for?
Sadly I think it'd be a bit of a curse word to change the output direction so i could build a kart with a couple of them.

Hmmmm...there is a possible way of changing the vert drive to horizontal,by a bevel box off summat (ride on mower?) Ive seen it done,but cant remember what was used.I'm sure I saw it on a obscure website somewhere!

Use an alternator to make a 12v generator. Lorry cooling fan on shaft and use for hovercraft project. Ride on mower gearbox / transaxle will give drive for a buggy.

powered merry go round..
if your looking at a kart i would say that youd be better off either ebaying the ones you have, or taking them to your local mower repair place and selling them there, and buy a decent horizontal shaft mower engine - you may even work out a part ex with the mower guy. This would be a far easier route than bevel boxes etc.

I've seen two-stroke vertical-shaft engines that have been turned around to sit horizontal. On a two stroke the only thing you need to do is adapt the intake manifold to turn the carburettor around so that it sits the right way up.
In terms of things that you can do with a vertical shaft, as mentioned before, they work well for a hovercraft lift fan.

Depending on the engine, two or four strokers should work OK if you flip them to run the shaft horizontal and the head canted down to 45 degrees ish. I did it with great success for my chopper!

Is there a particular reason a diff has to run with the shaft horizontal? Just thinking that with a horizontal chain drive from a diff flange, the engine crank can remain vertical.
I am still after a Honda GX25 or GX35. They're dry sump four stroke strimmer motors with a cambelt in the crankcase which can be run at any angle. Supposedly they're super quiet so would make a good camping generator.

Thanks for the ideas - so far i've just ended up repairing 4 of the mowers but i've still got decent spare engines! Hard to kill doesn't quite sum it up for those!

Use an alternator to make a 12v generator. If you can couple up an old tumble drier motor or any other big brushless squirrel cage motor it might be possible make a mains generator pretty simply. Instructions over here. Big high voltage DC capacitors can be salvaged from old computer monitors. I have a biscuit tin full of them. I guess the engine would need a governor fitted (mowers usually do though, don't they?) and in good order for it to work reliably as the speed needs to stay constant under load. |

Why not bolt a diff to the underside of the engine, then have shafts coming out to the rear wheels? Easy way to make a rwd cart  |

There's no clutch set up on the mower engines, guess i could use a belt driving a pulley on the diff and engage drive by tightening it. But i think the whole diff set up would be way more weight than these could handle.

in that case.... turbo it! ;D lol A small diff weighs what... 10kg? You weigh what... 70kg? And you're expecting it to pull you around with ease - which it will do  Or - take the spider gears from inside an old diff, to make your own 90 degree gearbox  |
