Hi,
Retired last year and finally got to repair my old Air wolf .177. It is an original. I had to put it in the closet for about 10+ years. it was fussy and consumed too much time.
So this is the first version with just the electronic trigger. Bought it used , and it is an extra FAC . Anyway , new battery , new seals
good cleaning and it works but has shot like garbage mostly. I bought a Huma reg and installed.
I Tried the huma at higher setting 140 bar , no resolution on the electronic settings, Just dialed it down to 110 , still the lowest setting is the best for accuracy. Any thing higher and the group open up. I plan on getting the 120-125 huma suggests.
Some problems with consistency, I shoot near 1 moa and then it opens opens up. It only shoots decent on the lowest electronic power setting.
I am thinking it is way over powered for accurate shooting, I am considering now replacing the main valve spring with something heavier if nothing else to give me resolution on the electronic power setting. Current one is about 13.3 in-lb, thinking of at least tripling it.
I did polish the barrel , it did help and tightened the groups. The barrel was loaded with lead dust and wax .
Even 10 + years ago , it never really shot all that well.
Just wondering if anyone else has made the journey here. advice appreciated.
