So....just joined this forum (already posted a bit of a rant about Huggett.... sorry). I feel very privileged to be here with so many who know so much more about PCPs than I and I am looking forward to learning from you all. One quick question (and I apologise if this has been done to death already). What is the best way to long term store a PCP? I have built up quite a collection of them and some do not get fired from year to year...but I cannot bear to be parted from them...that may be a familiar emotion/illness for many readers here? On paper it all seems quite simple, but then I get them out to decide which to move on and discover each one is VERY SPECIAL and cannot be sold. Yes, I have been infected with some sort of wonderful disease! So, if I can't sell them what is the best way to store them? Should I lube O rings etc? e.g. have an old MGBGT, in the winter I deflate tires, put battery on trickle charge etc.......... what is the best drill with PCPs? Discharge air VS keep it pressurised and so on?
