Can't pass smog

Trying to get my 2000 re-registered before Solvang.  Every year has been a
struggle, but this year it is not even close - Hydrocarbons at idle is the big
culprit.

2000, Solex carbs, cam.  Seems to run as good as it ever has, maybe 5k miles
since major rebuild 5 years ago.  I can smell a little unburned fuel at idle.

#1 plug is black, all others nice grey.
SK syncrometer (at idle) shows 3.5 for #1, 5 for all others (it has always
been this way, though.)
Compression for #1 is a little down from the others (always been this way, for
some reason.)
Timing is right on, electronic distributer, no wander at all.

Since car sat so much this winter, I wondered about a clogged something in the
solex, but all seems to be clear.
Any ideas on where to start?

ps - I've been off the list for a year or so, so feel a little funny asking
for help now...
