So, I am going to use a lawnmower differential with 13 teeth sprocket on it and 9 teeth on axle to get more speed then lawnmower originally had, linked by type 50 chain.

Type 40 is OK (commonalty used for bikes), and type 50 is overkill :-)
You can use this calculator to calculate top speed for you go kart.
I am going to have chain guard to keep chain from falling off during drive.
