Thank u…i got it it was the oring at the base of the stem
The convertible snap ring pliers are the worst. The metal is sheet-thin and the hinges are flimsy – the heads will flex and bend as soon as you try to put any pressure on them. I have a pair and it’s junk, makes me want to pull my hair out when I try to use them, but too stubborn to throw it in the trash. Get a solid pair like Ernest uses in his video, just make sure you get the right type that compresses the snap ring, not expand it.
Here’s a video for the 1st timers and a modified pointed needle noise snap ring pliers that compress or open the snap ring.
I also purchase those snap ring pliers, but they don’t close far enough for the snap ring to touch each end so for the OD to be at its smallest so the s-ring can clear the hole easy like on the video.
Great Idea GKU!!!
I think Ernest went to bed, I’ll be up a few more hours.
I’m not as good, but I hope I can help some.
This would be ideal http://www.amazon.com/Snap-Circlip-E-Clip-Retaining-Pliers/dp/B003R6K1BC
But you could use a small needle nose pliers or two small allen keys.
Insert into the holes and squeeze together until it becomes small enough to come out of the groove it’s in.
Be extra careful not to bend or loose the e-clip, it could slip and fly. Do it in a clear plastic bag.

How to remove circlip#10 piece?
Yes, the middle indicator leak hole (regulator O-ring failure hole) is the hardest one to figure out.
Because, it could be any one of the 4 O-rings on the regulator that is leaking, 2 – #8 O-ring and or #11 and or #15.
The #15 is a pain to change among them all, make sure to mic your setting before replacing it.

HP oring #15 is the one I replace the most, never seen oring 11 to fail—-it handle only regulated pressure. those 2 oring are the work horse on the cricket—they seal the piston rotor while in motion!
I will replace 11 and 15 I think it is regulator failure
what i noticed is the air push the regulator forward in spite of the presence of the spacer number 9 in the diagram but the regulator is moving with pressure for about 1 mill allowing the air to leak
i am really astonished i didnt replace that spacer so what happened?
if oring 11 and 15 are leaking it would also bleed out the same hole, also the regulated air on the reg housing 3×24 will also bleed out that hole. spacer #9 will not move with pressure unless the firing valve #3 inst screw in all the way. has all those oring has been replace also???
i used the 3.1 x 24.4 o’rings but still leaking from the same hole

Make sure your tube and reg are clean and free of corrosion or scratches. Check tube threads and breath holes for sharp burrs that might knick o-ring as it goes in. As an option to a larger size o-ring, Robert Lane has suggested using a few wraps of PTFE tape in the seal groove, and trim off any excess. https://www.youtube.com/watch?v=bctMCveyO7c
Seen this a lot, the oring goove is pitted / water corrosion —- if oring groove is smooth with no water corrosion use a larger oring 3.1 X 24.4 and use Molykote 55 to swell the oring. If heavily corroded and you don’t know how to remove them—send it to me I’ll make it look like new.
