Hook your bottle directly to the marker. If it shoots OK, then you know that the problem is in the remote. I have seen a remote collapse inside the hose and not allow enough flow through the hose. I have also seen the bottle connection not allow the valve to open the bottle fully. Attach the bottle, screw the valve all the way in and then back out about a 1/4 - 1/2 turn. I have seen them go to far. Make sure the problem is in the remote or the marker first.
