I'm sorry if this topic has been discussed but I've searched this forum completely.
My impact .22 is not reaching its maximum velocity. I have checked everything. At all setting at the max I have reached a maximum of 880 fps with JSB 18s, reg at 150bar, valve opened fully and by fully I mean completely taking off the adjuster. I have also added the delrin washer between the hammer seat and the hammer instead of o ring. Even then this is the maximum velocity.
Every things to my knowledge has been checked at factory specks, all orings are fine, no leak, guage has been checked. 6mm valve , the probe is in line with the barrel hole etc
When I checked the velocity, with the hammer adjuster screw also tightened with no play on max I got 850fps and on low power I got 890 fps. So I thought I have over tightened the fine tuner screw . Now with the wheel on MAX there is a 1mm play in the black fine tuner . I get 890 and when I lower the wheel to minimum I get 880, so there is no major difference with the power wheel
I cannot send the gun to any dealer as there is no dealer support etc here. Also I have a little experience of tuning pcps so I'm sure I can do what's required by myself
Please Help
