Very true!!! In the last few years, several Spits have been diagnosed with
this problem via this list. Everything you stated is valid, except for one
omission. There are *TWO* of these brass restrictors in the tank vent line.
The one you mention near the charcoal canister, and one near the tank. On
a Spit, it's inline, directly over the tank, almost dead center. I've found
that this rear one plugs up more often. Normally, they're full of varnish
and gum from dried gasoline.
Everything said also applies to TR6's and TR7's, though the location varies
slightly.
