Had a Dellorto SHA giving me fits because the bike would not idle. Saw all the tutorials of where the idle port was , but kept thinking it was on the brass tube. Today there was bright sunlight and i finally found the little bugger.
Cleaned it with a small wire from a wire brush , carburetor cleaner and an air compressor. The bike now idles perfectly.
Thanks to all you who tried to show me , but sometimes you have to find the hole yourself.
I have included pictures so the next guy will find it easier to clean.
