    Luis and rsingler thank you very much. Luis, can you get that into the VDH Manuals? Have not started tearing into the pilot yet, it’s my winter project when I get down to my boat. Think I read something about a ball bearing and a rocking boat.

    Finally, the bottom half of the poppet retainer assembly does NOT disassemble!

    That's the flange just to the left of the orange oring where the pin protrudes.
    Despite this diaphragm that looks like the knife edge slips inside the retainer:

    Part 99 knife edge is press fit inside the retainer and cannot be removed or serviced. They means that the famous "6 tiny bubbles per minute" that are "supposed to leak" from a properly tuned Pilot are actually likely a leak from a deteriorated knife edge seal against the extremely tiny oring #94.

    Can't be fixed, except by using the softest duro you can find for that oring.

    Buy Regulator Savvy. It's all explained there in great detail.

    The Smallest o ring is the almost impossible on to change.I know Pete Wolfinger made a tool to line it up.
