Great, thanks Dave, Harold, Tom et al. Those are all good places to check. I'll probably start this weekend and do as much of the easy stuff as I can. The vacuum leak didn't even come to mind - thanks for bringing it up. The CC is probably the last thing I'll look at after a retest. Thanks again.

Hi Make sure there is no vacuum leak at the vacuum advance solenoid. It is bolted behind the mixture control unit, right below the fuel distributor. Part number 101116, parts manual page 2.4.0 component number 27. Every solenoid I have seen so far was leaking! 100% of them! If this part is not sealed it will create a vacuum leak and the vacuum advance will be below specs. They all leak right where the electrical connections go inside the housing. It is best to remove the solenoid from the car and seal around the connectors with oxygen sensor safe silicone. It is important to use sensor safe silicone because if the vapors get sucked into the engine they will damage the sensor and make the emissions even worst. Good luck Greetings from Poland!
