You should always start shooting with an AGB all the way open. Doing that, if your gas port in the barrel is too small you will know right away without waisting ammo. As Klem says, it sounds more like the block is all the way open and you should be turning it closed. The suppressor is going to give you more back pressure in the gas system. Get the gun running properly without the suppressor to eliminate that variable in the mix, then once the rifle cycles to your liking put it back on and adjust as needed.
