I would squash a coil first

At 12.1, I'd be taking that extra coil off, Pete. The issue, to my mind, can often be down to the transfer port choking and not flowing the air quickly enough with the more rapid compression and pressure & temperature build-up. If an extra coil off dropped the power too much (I guess it won't), you can always put an extra washer or two in.

What make of spring is it please?
Plinkerer and Tinkerer
Quite common, my fwb sport, standard spring is very long with a huge amount of preload, to the extent you have to use a spring compressor to get the thing in. Maccari old school kit, Drop delrin spacer into the piston fit short spring & push breechblock home with one hand then screw retainer bolt in with the other.
Power went up to 14 ft lds. Had to take 3mm off the spacer before it went under the limit, now has barely any preload at all.
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
This kind of springer fickleness just makes one want to bang one's head against the wall. Probably a lot to be said for a TbT kit where the thing has been worked out already, and while that is an extra expense the time and frustration saved may well be worth it.
Not always the case, I had a V-mach kit once for my Prosport and I could not keep it under 12ftp, Steve even reduced the spring a couple of times, strange thing is, I fitted one of Tony Walls spring that matched the guide and it ran sweet as a nut without any more adjustment.
Far too many rifles to list now, all mainly British but the odd pesky foreigner has snuck in
