E99 question

[Flightfreak777]

I Have a Spyder E99 and the gun works great except for one thing. It seems when I dry shoot it, it spudders out but when there is a paintball in the chamber, it shoots clean. Any ideas? Still a useable gun but kinda annoying. I took apart the entire thing today and cleaned it and checked the rings and they're all fine. I'm kind of clueless but then again I'm not expert

replace all the orings. Even if they LOOK okay, they can still be worn out and not sealing properly. also, a few drops of synthetic oil in the asa before you air it up does wonders.

idk much about e99s but all spyders have problems with the cup seal take it out and oil it
