[FC] vacuum advance question

[Garry Parsley]

Bill,
  Did you recently rebuild, or have the distributer rebuilt? If so, it's very easy to install the cam lobe part (I forget the correct name at this point) 180 degrees off, which reverses the mechanical weights causing retard instead of advence. Everything looks good - but it ain't! Don't ask me how I know this! That one was a three week learning, I mean training,  experience.

  After setting the timing using a timing light, I noticed that when I rev the 
engine that the timing retards very far very fast (from 14 btdc to -4 btdc), 
and kind of "catches up" to where it should be over a few seconds. The 
vacuum advance appears to move instantaneously, however. If you give it too much 
gas too fast, it dies. Is this a symptom of a bad vacuum advance, or bad 
vacuum? Yes, I did check for vac leaks.

Note: thanks to everyone for the ideas about the electric fuel pump, new 
pump is on and fixed the problem.
