hey all, i have put an e1 frame on my cocker, and a new AIM adjustable primary regulator, since doing this, i barely get a hoppers worth of paint out of my bottle, iam using a 1.1 3000 pre set system, although i know i should use a minimum of 4500 surely it should not use up that much air ?, my bolt is the ****ty bog standard aluminium one, which has seen better days, can anyone shed any light on me prob ? cheers folks
