Seen this pic of the Dellorto DRLA mixture screws for Dellorto DRLA.

Mine have never had the washer or 0-ring.

Are these critical to smooth idling?
What is their purpose? I can't see any advantage to them unless it's to prevent any air leaking in through the brass thread of the screw.

I have the 0-rings but not the washers. I'll see if I can get some at my local hardware store.

response from dellorto:

my washers and o-rings missing. Will order them.
Anyone else have them missing, any ill effects, maybe unstable idling?
