at this stage of the game…I do not know where the mixture setting was when I got the car. Originally the motor always fired and attempted to idle but quickly stalled out( 5 seconds?) probably plug fouling. I stayed away from the mixture adjustment because of the bad vibes from reading threads on line. Eventually I had no choice but to start playing with it especially after completely rebuilding the air vane housing, rebuilding the wur, fpr, along with the fuel distributor itself. Things were getting better…..the motor would start and idle for minutes before plug fouling stalled the motor. Lots of vacuum leaks were fixed along with the coil wire to the distributor cap. Eventually started playing with the mixture screw and discovered the injector no flow point (injectors do not dispense gas when the air vane is at rest position) was learned. From the no flow point the mixture was always being en-richened because it was thought that the stalling was caused by lack of gas. But any enrichment beyond the injector no flow point (injectors do not spray gas when the air vane is at rest position) fouls the spark plugs. Motor starts and eventually plug fouling causes it to stall. Last night after pulling plugs several times and hand cleaning them I finally came to the realization that not only was there a black carbon soot on the plug but that they started to appear wet to me especially after stalling and trying a restart. Remember this is the first car that I ever bought not running….never had to use plug inspection to get a car running. So I decided to lean the mixture from the injector no flow point (injectors do not spray gas when the air vane is at rest position) and was surprised that the motor started as easily and idled for a longer period of time 10 minutes…15 minutes ….still running car in garage so I eventually would shut the motor off. Motor was starting to come up to temperature. I also still need to top off the coolant reservoir from the auxiliary air valve removal exercise. When I removed the plugs after leaning the mixture I realized that if the mixture is correct at idle that the plugs will have no discernible residue on them when removed.

Tonight will top off reservoir. Connect distributor vacuum advance. Place the bolts that connect the wur regulator to the block. Push it out of the garage and let it come up to full temperature. Still need to confirm that the throttle can be opened….have not done that yet.
