Stephen- my 1975 1.8 L-Jet gave black smoke with bad vacuum leaks.  
Wierd, huh?  Try the coolant temp sensor first, the call automobile 
atlanta for a kit with all the new 20 year old vacuum hoses that need 
replacing.  then plug in the vacuum lines to the vacuum advance/retard 
ports on the distributor, if your car is anything like mine.  It's lots 
cleaner and starts and runs well.  Also gets good mileage.
