HAM Sniper
Had an interesting hiccup after a simple reg adjustment turned into 2 days of not being able to get the gun to take any air. I have had this gun apart countless times, very familiar with it and its workings and had never had the issue. I tried all the tricks to get the poppet to seat, but it would not at all. A call to AOA also left them stumped as the Evol valve has literally two parts, the valve body and the poppet. No springs or inner seals. I decided just to remove the valve and inspect.
Removing the valve revealed that indeed the last bit of travel needed for the valve to close was not happening. There was nothing that jumped out at me that was holding it up, so my initial thought was valve pin was bent possibly? I just couldn't see how this was possible, so instead I just started turning the pin in circles inside the valve body. As I did this It got noticeably easier and the pin started to slide through the valve body more easily. I pulled the pin out again and noticed a bit of "tarnish" going on about 2/3 the way towards the hammer side. I worked this away just with my fingers until it would slide in the body mostly effortless. Then I put a very tiny amount of ultimox on the pin, and wala sliding free and clear. I reinstalled the valve and all other parts, hooked up compressor and problem solved.
My guess is this bit of crud had also been causing issues I hadn't noticed like valve sticking on firing or closing. On a side note, I was going to replace the two o rings on the outside of the valve body but they were absolutely flawless and looked brand new. Just thought I would share my findings incase this becomes an issue for anyone else.
