I wouldn't think the direction of the hammer spring would matter???

Will see on Wednesday if it makes a difference.

They use a progressively wound spring. I’ve never attempted to install it incorrectly. But it’s highly likely it compresses differently if installed incorrectly.
Not sure if that would result in variables though.

Does you assembly include the intertia weight and spring? Inside the hammer?

Yes it does.

Will assume PEG is actually REG ?
If volumes are that small it is no wonder why these rifles are Low ES ... but lack anything close to what larger plenum PCP's are producing for power these days.

That is why I installed external plenums.

Report Back:

Started shooting 5 shots groups with 25.39 MRD's at 25m indoors yesterday.
After 5 shots I adjusted the hammer spring a quarter turn at a time. Shot 5 more shots to settle the spring, and then shot groups.
When I had them just about go through the same hole, I started fine tuning with very small adjustments to the hammer spring.
I stopped when I got the smallest groups.
I then moved back to 50m, and the rifle again produced excellent groups.

It was clear from the outset that the rifle is very sensitive to adjustments on the hammer spring.
The vibration that was evident before, has now disappeared.
Velocity was right on 930fps.

The RAW is back to shooting like I know it can!
