Your head is wrong mounted. Wateroutlet should be on the top where the inlet is.

There must be ring in the cylinder with a small hole that must be on the same place as the inlet and outlet. I've add a picture for understanding.

Take a Pic of the head and the cylinder. It's possible that your head has a small hole on the inlet side like a BZM head. I will take of the head of my polini engine when I'm at home to show you what I mean.
That's correct what kitty says this transmission is not made for the power of a polini engine.
