The BT-4 ERC is not shooting. I adjusted the screw on the sear and finally got it to cycle not air'd up. Once I air it up though. It just shoots once or twice, then I only hear the solenoid click, then it will shoot again once or twice here and there.. I am going to assume the sear screw needs in more, but not sure. I am out of air right now, but trying to figure it out

Could it be a board setting issue? It's not my marker so I am not even sure what the settings are. Does anyone know the factory settings or recommended settings for the APE Boards for these markers?

If he has the stock board then the setting are not the problem. The sear screw could be adjusted a little more. Also try changing the battery use Duracell or Energizer.

Going to get my tank filled tomorrow and try a new battery. Hopefully that fixes it.
