i have a 12 hp lawn mower engine that is almost brand new but the shaft is vertical. anyone have any ideas how i could hook it up so i could run my cart with it which needs a horizontal, or would it be better and cheaper to sell my vertical shaft engine and buy a horizontal?

You could run a Right angle gearbox, Your best bet, Or using the same transmission they use in racing mowers. <- dont last long.
I have tried using my vertical opposed twin several different ways, You will be better off trading it for a horizontal engine. I eventually did, its just a pain, more complicated, less reliable, and You loose a lot of power through all the belts, chains and rotation changes.
If your going to do it though, Just get a right angle gear box, Theres some on ebay, I just bought one, their industrial, heavy duty (mine was 40bucks). And Run chain, or cogged belt to that from the engine. Don't V-belt it. I believe thats your best and cheapest option for the vertical motor.
Your best option overall, however, is to just sell it for a horizontal motor.

You could try doing a belt 90 degrees but, the belt needs to be thick and you get slip with it too.

You may be able to sell on Ebay or Craigslist the 12HP Vertical engine, then replace it with a cheap horizontal 6.5 or 11HP Honda Clone.

mcmastercarr sells 90* gear boxes with built in gear reduction for industrial applications that might work. They are a little pricey though, so your best bet would be to sell/trade for a horizontal shaft.
