When you have a new motor, it will push the sleeve out if you try to turn it with no head on it. Since these are ringless engines, the pinch between the cylinder and piston are what creates the compression required to run.

When you say not sucking fuel, how do you mean, it isn't supposed to suck fuel, it's supposed to get pushed in my exhaust pressure. Have you checked your lines for leaks and tried turning the motor over with your thumb over the exhaust?
