Reply To: Vulcan .22 Speed low first 3 to 4 shots
You tried adjusting the HSTA, there’s a lot of time I have corrected the low speed idle. It’s a long proses, 1st adjust HSTA till speed start to slow down than shoot a mag full let it idle till the time you experance the slow speed. This is trouble shooting the reg for leaky piston delrine. When they leak a little and seal the regulated pressure will be higher so the HS will not open the valve fully till pressure is back to normal — so that is way it’s consistent while you are shooting.
You dont don’t need a whole new reg.
Just resurface the delrine seat.
that reg is one of the best,
