Puzzling power problem

[Solo1]

I have a Logun Solo (FX Typhoon) in .177 running at 11.4 ft'lbs. It is fitted with a Ben Taylor & Son regulator and has always been remarkably consistent and economical on air, giving 100+ full-power shots over the last 5 years or so (over 20,000 pellets).

A problem has arisen whereby the first shot after the gun has been left overnight is down to about 8 ft/lbs (around 660 fps). The next 3 or 4 shots show an increase in power so that by the 4th or 5th shot the gun has attained the full 11.4 ft/lbs again. It will then remain on full power during a normal day's shooting. This problem still occurs whether the cylinder has the full 230 bar (recommended by Ben) or has run down to 100 bar or so.

I've replaced all O-rings and seals (except inside the regulator) and cannot detect any air leaks, so I am at a loss as to what might be causing this problem. Ben Taylor has retired now so I can't get it serviced by him. Does anyone have any ideas on what might be causing this problem? Any help would be greatly appreciated.

looking like the reg needs a service

Thanks for the reply.

Ben Taylor has retired and his son, so I'm told, no longer works on air rifles so it isn't possible to contact either of them for a service to the regulator. Does anyone know anybody that services regulators that would be willing to service my BTAS regulator?

Thanks Sniper. I've already done numerous searches on Youtube and there isn't a service guide or regulator video listed under Ben Taylor, in fact, the only Ben Taylor I found was a singer/musician. Plenty under Robert Lane regs though.

Thanks for the bay link. I've been looking at their tutorials on the Solo on Youtube. The regulators are different in design to the Ben Taylor models but, overall, they seem to be relatively easy to strip and service. Thanks again for taking the trouble to reply.
