    hw 80

    I got a hw 80 which I purchased in the 1980,s, fitted a new piston seal and was surprised that it is a slack fit, have they changed the diameter of the new piston seals, years ago I always had to size them

    I got a new one about a year and a half ago, the piston would fall down the compression tube under gravity, but would stop with a finger over the transfer port. Which is exactly what I wanted, but I was surprised to get it right out of the box.
