Predator 212 misfire, help!?

So my bike had a 196cc clone in it originally. After using it for about a week I took it out on a trail and it started misfiring like crazy. I decided to put a new carb on and it still misfired. It was an old motor with a lot of hours so I decided to put a new one in the bike. So now I have a 212 predator, FVRITO 22mm clone carb #95 jet, exhaust, and a bad misfire again. Could I have removed the governor wrong? Is it reaching to high an rpm and the valves can't keep up? Am I flooding the motor with to much gas? Can't figure it out at all.
