Ok so I serviced my G-200Bs and they work well. However, I have a problem child.
I have a g-250 that was free-flowing. I did an underhaul on it by cleaning it and changing out the seat, and replacing the dynamic o-rings on the orifice and the adjuster knob. I also replaced the VIVA o-ring. The o-rings on the poppet look good so I just re-lubed them and reused them.
Now here is the problem. When I reassembled it I cannot get it to stop free-flowing, even if the lever is way low. I get it to a rather soft free-flow and then when I breath it the free-flow increases. However, if I turn in the knob about half-way in I can get it so stop. Being the knob adjusts the spring tension I figure the spring is bad, but I thought they stiffen with age. The IP from the first stage is 140 psi.
What do you guys think? Is my Spidey Sense correct about the spring or can it be something else like the balance chamber? The balance chamber is the older style black version.
