Kart Blueprinted

"I can use two engines and a core of all off the back of a tractor to ride a kart?
I have two engines, both in the same power and a shaft (5 speed / N / R) I wondered if there was a platform so that I can my kart to where you can continue. This is all I know. And if I can I can to change or scroll down, while I'm still going at a good speed? I also know that should a clutch team to simple things, but that for me. And if anyone can, can someone give me some go-kart plans, as planes suspension, steering column plans, drawings or any other good that I can help with this great project? Thanks, John
What you need two engines may look cleaner, but getting a bigger engine would simplify the matter
