Will a 68T Sprocket from Wish fit with the chain and mounts of a 2 stroke kit?

That's for a pocket bike, it won't work.
If you use a 48t from a dealer here, or the seller you got the kit from, you'll have plenty of power for most hills, unless you are over 100kg.

Honestly, if you weigh less than 100kg, I'd put the bike together with the stock (usually 44t) sprocket and see how it goes.
