AA S200 Bells & Whistles - Poor Results

[rabbitslayer]

Don't know about the reg not "breathing" I've only fitted Lane ones that need a breather hole drilling take it the Huma one doesn't and is a sealed system?

It's not a sealed system. It needs to breath but instead of drilling a hole, you remove the 'o' ring from the brass end plug (on the S200 cylinder) before you refit it and don't tighten the end plug totally shut. You leave a small gap, about the thickness of a sheet of paper.

dunno but the adjustments you make to the firing valve spring tension together with the strength of the hammer spring affects the opening of the firing valve. it can take a lot of testing to get the right balance.

Hmm... that means having to empty the air tube each time I need to alter the firing valve spring.. Ah well. I'll start with the hammer spring and see how far I can back it off and what the outcome is before touching the valve gate spring again.
