As per my post in the general section: the 107 is probably working better than new since yesterday, thanks to Ped's skills and knowledge.
Amazing. Ok, it's not the most efficient pumper. But 11.1 ft/lbs at 12 easy pumps ain't bad either for a .177 from 1948/49.
If only DT Fletcher could read that I have finally managed to solve the droopy pump arm issue lol (RIP).
It was down to a badly worn pump arm link pin hole and pin.
To up power, I tried a new pump cup and a leather pump seal from JG Airguns, both to no avail.
In came Ped with this double o-ring'd pump head. And an o-ring'd pellet probe.
It was a bit tricky to find the exact correct pump rod length. Now it cams over nicely.
Result.
