Low power hums reg belville wash config

[blam62]

Does anyone have the belville washer configuration for a huma regulator that goes in a Crosman 1720T?

Already reached out to them but won’t hear from them for a few days. Was hoping someone on here may be able to help me get up and running quicker

What power are you getting with this setup? I’m shooting a 10.3 g pellet and only get 375fps. I’ve tried both a light weight hammer and the stock hammer. Not much difference. I have. .140 TP in it as well

Shooting 8.4's at about 780fps. Huma set at about 95 bar. Stroke at about 8.5, stock hammer. Spring maxed out at 7 turns. That belleville configuration was as received from Huma (Marauder Pistol and 1720t are the same regulator)

Thank you. I will give these setting a try.

And, in addition to enlarging your transfer port, you'll want to enlarge (drill out) the valve opening as well...
