Sorting out URQ

[DGraber460@aol.com]

Tonight tried to set the timing on the URQ. As I moved the distributor back 
and forth, the timing mark would not move until I reached what seemed to be a 
limit point going both directions. Is this the much talked about hall sender 
at work?
The car is running _very_ rich. If I pull the largest vacuum hose from the 
intake, the idle increases about 200-400 RPM! Plugs are the blackest/sootiest 
I have ever seen on an engine that runs. Sounds like open loop mode?
Where do I go from here to rectify this?
