PCP I didn’t mean for this to happen

[FL22]

I have removed and rebuilt the reg in my Cricket II now several times trying to find and fix a leak.

I have not yet tried to do any tuning, haven’t messed with the hammer spring.

I measured the regulator with my digital caliper to ensure that I put it back exactly the same every time.

The printout I received from AOA shows JSB exact heavy 10.34, 5 shot average 954FPS ES 18 SD 7

After it was broken in, I made an initial 50 shot session AEA 10.3, 898FPS ES 18 SD 3

So today I decided to pull the regulator clean the belleville washers and give the MicroLubrol a try.

50 shots AEA 10.3, 873FPS ES 7 SD 2

I’m guessing that the tighter numbers were caused by me not getting the regulator set pressure exactly the same, I think that because of the FPS being lower.

Is that likely?

You should have left well enough alone.

You should have left well enough alone.

That sentiment goes largely against human nature.

No, I will begin to work on finding the best balance of power and efficiency.

You probably have it down pretty good now, but how quick can you get in and pull the reg out? If i am correct the variables here are; the new lube, your workmanship, the new seals. Hmm it could even just be that its "more" broken-in lol. I would definitely be happy with those numbers though! Less fps, but tighter spread....my S510 has done the exact same thing over a longer time period, but ive done nothing internally. I'd shoot it a bit more (couple hundred pellets) without touching internals and knock that variable out of the mix at least.

I’ve had it apart so many times that honestly after it’s degassed, I can have the regulator pulled in under five minutes easily.

What concerns me is wearing out the plastic adjuster. That’s why sub 12 airgunners made a replacement for the one in his videos.

One more item to add to the list of variables is that I still do not have the exact depth for the valve spring tensioner. when I originally took the gun apart, that adjuster was loose, I could see were it was struck by a punch including the threads. I’m assuming that was supposed to lock it in.

I’ve tried looking all over the web and all I can find is some dated information for a cricket 1. I guess since I have the leak addressed, I will go ahead and email Shane at AOA. That’s why I have been waiting so I’m not just bugging him with question after question.

I destroyed the valve in my Airacuda because I was using information that was current due to design changes that had taken place. However, the valve was older and not the same length so the increased tension damaged it.
