Couldn't find "World Star 40" on the Internet but, as Chuck W mentioned, if it is a flat bottomed wing it will tend to rise with added throttle. That's what it's designed to do. You could add down thrust to the engine by adding washers at back mount bolts or shim the rear of the wing up, but you will trade off other flight characteristics.

Raising both ailerons has the effect of lowering the angle of attack and will do it. Try raising both 1/8" at a time.

There is a saying: "Never try to teach a pig to sing. It wastes your time and annoys the pig." If you're looking for speed you need a different airfoil and design than a trainer.
