Mine just has one hole for each auxiliary venturi, not three holes per. I can tell this has been rebuilt before by some of the skinned screws, although not badly damaged. I THOUGHT I remembered seeing some sort of gasket used in there in the past, on other's carbs! When I took it apart, though, it had tiny rubber O-rings in there, or the shredded remains of them, anyhow. So, what sort of gasket is original, and how thick? Rubber, paper, cork? Thanks very much, the THICKNESS is highly important!

Trying to rebuild a DCH 340 carb, and so far, so good. BUT - I need to know what the trick is to replace the O-rings on the auxiliary venturis! I can't seem to get them to stay put when sliding the venturi in. OR they go in, but then bulge out into the hole in the carb. What the way to do this? A MILLION thanks for any hep!
