It is always a pain in the a** thing to get the '69 2000 Solex 'B' cam  
to pass smog - all smog equipment was removed long ago.  Had to make  
only 4 trips to the smog station this year, so it is getting easier  
<g>.  The real trick was to retard timing all the way to 0 - my  
adjustment would only allow me to go to about 5 degrees, so I removed  
the bolt completely and got the lowest hydrocarbon and CO readings at  
around 0 degrees.  At this point it would barely achieve 2500 rpm, but  
passed, and at idle speed it passed easily.  Of course, the pilot  
screws had to be leaned out some as well, but overdoing it resulted in  
CO skyrocketing.

Spent the afternoon getting it to run right again - it does like  
things on the 'rich' side with timing at almost 20 degrees (Boone  
distributor).  Solvang, here we come!
