Rotisserie balancing

I'm hoping someone can help me here. I have the car on the rotisserie. The complete drivetrain is removed, the fuel tank is removed, and the left front suspension is removed. The right side is coming off. Ones I start tilting this thing it either tries to run away or takes my full 250lbs to get to move. I have the balancing point as high as I can get it. The rotisserie is a titan 4500lb. I've attached some pictures. Can some offer some input please? This is my first rotisserie experience.
