Thanks Eben! I think when I put it back together I'll rotate the body so the venturi faces down the inhalation horn. I heard that can improve performance. I'm open to all advice. I am assuming I should test lever height on a full 2250 tank given the fact it breathes easier at higher pressures (I think). MarkSurfLung wrote:Wow. That one is a treasure. Congrats on a great find.
If you know where to find that article i'd love to read it. Didn't see it in the Manuals section.SurfLung wrote:Greg Barlow sent me an article that ran through the whole thing.
Interesting. When I opened this puppy up the first time I had to take the standard 7 c-clips off first. The main diaphram was an old two-stage one with the prongs flattened. It looked like it hadn't been removed ever. The hose clamps were original voit ones. The hoses, mouthpiece, one-way mushroom valves and duckbill were most definitely all original and unusable. I ended up having to replace the 2 phenolic washers as they were a leak point. Odd that someone would replace only the lever?
