Shockers are a breeze to tech. In fact, that's the gun that I first seriously learned, mainly because I had to know it well to keep it running, which I have come to realize is really the key to all of them. Mine opened my eyes to the wide world of regs, solenoids, operating pressure dynamics, proper lubrication, timing, etc. I love the fact that all of their parts are relatively large and most often only need a simple cleaning and greasing. I will likely soon buy an Impulse to learn them well, which I estimate to be in about a month or so. Meanwhile, if I'm in the same place as you are at the time, or if you can fly me over to where you are, I'd be glad to do all the work you can give me.
By the way, which email would that be?
