  Bypass ballast resistor for now (just run 12v to coil). It can be
  added back once engine is up. Ensure polarity is correct.

  Watch air sensor plate closely while starter motor turns engine. It
  must move down. If it doesn't, is either bound or engine is sucking
  air elsewhere.

  Disconnect spark advance. Until you're on Route 50 you won't need it.
  Could be potential problem (Martin G's reference to Darren B helping
  me dealt with an over-advance condition).

  Since you've no idea where fuel mixture screw is currently set, try this:
  1) crack throttle plates a reasonable amount with lower set screw
  (just like a carburetor!). This will be temporary idle once engine is up.
  2) remove idle speed motor for now. Cap take off under fuel
  distributor with a 3/4" vacuum plug. Add a 3/4" ball valve to cold
  start tube where idle speed motor used to be. Leave other end LOOSE
  (yes, a purposeful adjustable vacuum leak).
  If fuel mixture is unreasonably rich, this will let you slowly add
  unmetered air. Merely opening throttle plates won't help because over
  rich condition will increase correspondingly. Might work, might not.
  If engine does catch, you can back off mixture screw as ball valve is
  closed.

  If fuel mixture is too lean, pressing down air sensor plate manually
  (in MICRO amounts) will richen for whatever throttle plate position.

  BTW: when you mention pulling the plugs, are you actually removing
  them or simply disconnecting wires? Guarantee engine won't run with
  big spark plug hole.

  BBTW: you're not running the original coil are you? If so, give Rich
  the comfy chair (thought you might be able to use a little Python
  humor about now). A real coil is only $25. Ask Louie G what one did
  for him.

  Wouldn't it be nice if PRV ran without valve covers in place? Would
  let you watch valve train... 

  If Darren B gets you running by phone, please post the results online.
  Am sure a lot of people have been watching this more closely than As
  the World Turns.

  BBBTW: #5335 is only allowed to leave your parking lot under its own
  power. Did not lay around on wet pavement in the dark for anyone
  else's benefit.
