Re: Lost velocity when going from CO2 to AIR ?
relax... I repair, build, modify mechanics & some electronics every day and I know my limits.
3 shims are in the regulator. First 2 to come out are identical in size and color. Their color was your standard metal but with a slight tinge of red. Almost as if the color was washed off and left a tinge behind. The 3rd and last spacer to come out was half the thickness of the 1st 2 and had no appearance of any colors at all, just metal.
So what does this all mean?
