Tone, the o ring won't "run in " as such , the lube however will take a while to move about and settle down, just make sure it isn't dieseling a little. If you can find a good spring , that would be better, but as long as you have more than 10 mm preload your spring is unlikely to hop off the guide .
Don't forget tinbums new springs are excellent, and available in three sizes .
I am about to build and set up a 24 mm 80. With a 31 coil one, will let you know how it goes

Hi Nick, thanks ever so much for the input.

Running very minimal lube now after the crazy power I saw following earlier build. I'll obviously degrease again and apply ever-so-sparingly again. I could detect a very feint aroma of combustion, but no visible evidence and consistency is amazing.

It is running one of Nick's springs.

Twice shortened already. I'll shorten more as the threaded portion of the end block is circa 19mm, so there's scope to shorten further whilst still retaining the 10mm preload as you point out.

Thank you.

That sounds good , looks like just a little off the spring, should sort it .

My LGV pistoned 80 is now running a tbt spring, I got the full length one & had to chop a fair bit off, that still landed it slightly hot, so I took another half a coil & it's bang on.

I was going to take 1 coil off, but thought better of it seeing how much of the spring length a whole coil actually is.

I'll hopefully get the time to strip it and play on Wednesday.

I've just had a quick look at the barrel vertical play....if I push the latch firmly towards the cylinder the play goes away. Like it did when I just tried the barrel, hinge bolt and cylinder. So it might just be the spring that's gone weaker? I've just ordered one from Chambers, so fingers crossed......
