Why won't my TDR fill?

[trumpetier]

My recently acquired TDR was only running at just over 9. So stripped it down and adjusted the FP as mine was only 55mm,hoping this may resolve the issue. However when I tried to fill the gun, nothing. I've tried filling it cocked and uncocked, ideas please ?

Are you filling using a pump or cylinder.

Empty dive bottle maybe? And 57mm is about right for pot. Rog

Using a bottle, plenty of air in it. FP set to 57. I've not touched the fill valve, but there is no air getting into the gun at all.

Does air come out of bottle when not connected to fill valve, I only ask this as had a problem with my bottle last week, full bottle but air wouldn't come out, it was valve on bottle. Rog
