I have had a Huben K1 for the past 4 years (2018 model) and taken it apart a few times to sort out leaks and even rebuilt the regulator so I know my way around the gun.
However, recently, when I shoot the gun (Reg 16mpa, Air cylinder 240bar, power adjuster 15 clicks from closed), it buzzes continuously and dumps all the air.
I recall reading this may be caused by an indexing issue and is caused by an improper regulator and delivery valve adjustment. I have played around with the reg pressure and power adjuster settings and I always make sure the cylinder pressure doesn't go down below the reg pressure, but whatever I try I always have the same problem.
But, I can't for the life of me work out what is the problem. Any ideas where to start?
