Recocking problem with low pressure kit??

I just installed the low pressure kit on my a-5 with a palmer fatty reg and a crossfire 68/3000 tank. The gun works 99 percent of the time with paint in it, but it won't dryfire without putting your hand over the barrel to provide backpressure. If you don't, the guns just goes uncontrollably auto-fire and i have to either cut the air, or grab the handle to recock it before it runs my tank dry. Every now and then, it will even does this with paint in it, causing a paintball chopping mess that is a pain to clean. Now, I've been looking into this LPK for a while and tippmann never mentioned not being able to dry fire thegun due to backpressure problems, this is simply a pain in the neck (running low on paintballs before simply meant a dryfire mixed in with some shots, letting me know my hopper was almost out......now it means stripping the marker to clean the dang thing). Anyone come across this problem and fixed/improved it. Also, would putting a lighter rear spring in help, since this would cause less force being needed to recock the gun?

a-5 with e-grip, jcs double trigger, 6 position car stock, nw spoon drop forward, palmer fatty reg set around 300, LPK, and that's about it. I did notice that the cocking knob seems to have the slightest little stick when I first pull back on it. I don't really remember if it had that before I did the LPK because it was running fine so I wasn't paying attention to that. As soon as I pull back and it starts moving though.....it's smooth after that.

I had the same problem, but mine was due to an x-chamber converted to a volumizer. I got it working perfectly after some amount of work.

I called tippmann and they told me about the pressure also.....I forgot to mention in my post however that I've had the reg set from 300 to 450 with no change. Tippmann seems to think it is either a bad reg, or a problem with the srping pressure since I am using an aftermarket stock.

If you saw a pressure increase on the LP gauge when the turned the regulator up then there is likely nothing wrong with it. Have you oiled the "O" ring on the hammer? The after-market stock may interfer with the spring. Also run a few drops of oil through the regulator.

Please enlighten me on how one can misalign the power valve inside the power tube with the shells bolted closed around it and the valve screws installed holding the valve in position?
