hey, im new to this forum!

I purchased my A5 quite some time ago, i have a flatline barrel on it along with a MP5 Foldable Stock on the gun. I bought a Respnse trigger for it last night. I installed it this morning and everything went smooth. Well when i hooked up the CO2 i was expecting a hisss or a air leak sound but nothing! i was in shock. Anyways, i went about tuning the trigger, Here are my results, Stock setting at fully closed shoots normally like it did without the trigger upgrade. turned and turned until completely open still shooting the same way!

I looked at this thread ( http://www.tippmann.com/forum/wwf77a/forum_posts.asp?TID=161 178&PN=1) someone said that if i get oil in the lines that would freeze it up, Well in the instructions it says to put a few drops on the piston intake/exhaust? When i get home i will try to replace those hoses and see if that works...lastly i remeber looking at the piston, everytime i squeeze the trigger the piston goes forward, and not back. im assuming that is the problem?
