Can i use a lawnmower motor for my diy go kart?

Depends entirely on what you've got but the easiest solution to avoid more components and friction losses is just to mount it on it's side, probably enabled by removing the fuel tank separately (which isn't a bad idea anyway as it means you can make it safer and bigger!), and replace the end connector where the blade would normally attach for a belt-wheel instead and run that down to rotate your axle, but as I say it's entirely dependant on what you want to build / resources available.

so i put the fuel tank on top? and put a tube in the hole where the fuel needs to go?

but will the carburettor work on it's side? maybe a motorbike 2 stroke 125cc. would be better as you have a vertical output with gears if you include the crunch box.

We’re missing a chunk of info here but my guess is that if it’s a two-stroke then it might need some small fuel-assist pump. That said, thinking about the other 2-strokes I’ve got on things like hedge cutters and strummers, they don’t seem to mind what way up they are so long as the fuel pipe is wet. The old one I’ve got put by is a 4 stroke and I doubt will care.

I would have thought that the biggest downside of keeping ‘as is’ and fitting a transverse coupler would be that the starting torque to get moving would be crippling if you’re just relying on the simple slip clutch that I’d expect to find on a mower engine?

where to buy it and how much does it cost?

hey on the lawnmower engine can u put it on his side i thought it will not work then but u know how to use it if it is horizontal?

Have a look at a 100 national or international racing kart, chain drive no clutch and no electrics or pumps.

that is a vertical motor i have a horizontal motor

The motor does not know that.
