OK, problem to date:  '82 = Westy, air-cooled, no oxygen sensor (no connector for it).  Engine starts = and runs fine when ambient temperature is under 70F.  When engine warms up, = begins to miss, run rich, and finally chokes out.  When ambient = temperature is over 70F, engine starts badly, misses, smokes and chokes = out.
 
Attempts to date:
Replaced -- Temp Sensor = #2
          &nbs= p;       Plugs
          &nbs= p;       Points & condenser
          &nbs= p;       Rotor & Cap
          &nbs= p;      
Checked per Haynes -- = AFM
          &nbs= p;            = ;           Cold Start Valve 
          &nbs= p;            = ;           Fuel Injectors
          &nbs= p;            = ;           Aux. Air Valve
          &nbs= p;            = ;           Thermo Time Switch 
All meet electrical specs at each point and checking = from the harness per the book. 
 
Question:  Whats Left? Combi Relay?, Fuel = Pressure Regulator?
Any assistance would be helpful. 
 
P.S.
I have also checked and cleaned all ground straps = from battery compartment and from the tranny.
