Power troubles
Posted: Tue Jun 26, 2018 6:46 pm
I have an airarms 410 carbine with a airmasters 88 (dave welham ) regulator fitted it has bee unused for about 3 years and I have decided to sell it .
Unfortunately when i got it out to check it over it had developed an air leak . I managed to narrow this down to the reg, I decided that as I like a tinker and also to find out how stuff works I would have ago to fix it .Also I would have to take it to a gunsmith to sort it ,so I thought even if I cant fix it will still be going there .
Anyway stripped gun got out reg replaced outer o rings and the one on the stem inside the reg re assembled it all filled it and much to my surprise no leak ! then i thought even though I made sure everything went back in as it came out I ought to check the power which was 7.5 ftlbs. so i took out the reg again and made a slight adjustment and checked again this time 5ftlbs . so out it came again adjusted reg again in the opposite way from last time ,tested 2ftlbs !
Now i am really confused and on the verge of taking it to the gunsmiths to sort it , but would really like the satisfaction of doing it myself .
So i am hoping that one or more of you people with a lot more experience and knowledge might be able to point me in the right direction.
As i typed this a thought has occurred to me I did notice the bit of the firing pot that is left was loose , not sure if this would have any bearing on the problem.
thanks in advance
