Well, since I totally crashed Phil's thread here, and in the interest of not reinventing the wheel, I'm going to ask another question here that at least pertains to the diaphragm carburetor I've been talking about.
So I've finally got around to rebuilding the carburetor, and while disassembling, removed the idle and high speed mixture adjusting screws...was expecting to see rubber o-rings under the brass washer.
What I think I see under the washer of the high speed adjustment is a plastic insert ?
I hesitate to remove it, because it's close to an eighth of an inch thick...and the o-ring in the rebuild kit is nowhere near that thick.
And I haven't yet got the brass washer removed from the idle side, seems almost impregnated into the seal.
Am I thinking correctly folks, @markus , @oldcarcbx , or is this perhaps what a gas soaked, petrified o-ring looks like ?
Thanks.
