You should immediately back out of this fight. I'm a Black Belt in Karate and Brown Belt in Jujitsu and I would never take a fight like this. However, if you insist...

When the bell rings, go straight to your back. Try and take him into your guard and not full mount or side mount. Although, if he gets side mount or full mount, hopefully your technical skill can overcome it. My Jujitsu Master is all of 150 pounds, I'm 225, and he can tap my arse out from in no time when I start in the mount position.

But again, I would seriously consider backing out of this fight.
