Guys/gals, I have an interesting problem. 
I just adjusted the  timing and went on a test drive. Ran great! THEN I 
remembered I forgot the vac  advance hose. Reinstalled the hose, I drove more. 
Same old problem.  
Removed and plugged the hose, Ran OK
The vac advance does move when I  blip the throttle.


What is the problem? On slowly cruising main  drag, light load, light 
pedal, the car wants to "Bump" a little. As the season  goes on the bump  i will 
increase in intensity. 
Points, Condenser,  wires all new.


My initials are not LC/LC so I need your  suggestions.
