Single spring guide Vs two

With a massively inefficent transfer port passing through 90 degress to facilitate the compact design, they wacked in a big mainspring and heavy weighting to the piston to compensate.
The compression parameter then crosses the margins and flashes over for fun with even a hint oil...and i do mean a hint ....
First turn around the mainspring guide, or better still throw it into a scrap bin very hard so it damages and you can never use it again....then beat it with a hammer to make sure.
Yep, your talking to a guy who has been tuning this bstard thing for years.
My compardres all seem to like the thing and insist on buying them and me then tuning them....bit of a nuisance getting apart and back together but im on my 15th.
Replace the guide with one of Delrin, fitted conventionally.
I prefer a very long single guide, maintaining spring straightness to all the spring length external to the piston when in the fired situation.
Due to a well fitting Delrin or Techaform guide, it now negates any need for emoilents and can be run dry.
Clean it out many times and your now close to some semblance of an accurate shooter.
Thanks Clarky sound advice, interested why you go the single guide Vs two one at each end, also your views on lining the piston to prevent lube entering the chamber
Now's the time to enjoy oneself
