Default FS-120 MKIII - Leaking on Pressure Regulator

Dear Friends,
Ive got a FS-120 MKIII, that after 5 flights begun to leak on pressure regulator.
The High-end needle is not properly working, I can turn it like 1 full turn before it makes any slight difference.
Also, I have a Sullivan Glow Driver installed on it, wich causes it to not quit in flight.
BUT... It is weaker from 3/4 to full throttle than Half Throttle and lower...
It is installed on a The Worls Model Velox, but she is flying totally "hanged". The tail seems heavy eventhough it is on perfect CG. The funny part is that it does not "hang" when on half throttle.

Could anyone please help me?
Thank you.
