77 CA Spider ignition questions

[Jon Pike <jhpike@domain.elided>]

Hello group..

In going thru my Spider's ignition system..  I notice that it originally 
was a twin point setup,  with a vaccum switch to change from one set to 
the other, to vary the timing.

Of course,  the second set isn't there,  there is no wire and no vaccum 
switch.  I finally found the port to the manifold,  with a rubber plug 
covering it.

How badly do I need this?  Will an astute smog inspector find it missing 
(hmmm good question)  
Assuming I do need one for proper operation,  any ideas on where one 
might find one?  Anyone parting out a car?

The second ignition question..  I have a Marelli 166 (?) distributor.. 
and one of the advance springs is loose,  has no tension till part 
advance,  the other has tension from the beginning..  Both springs seem 
hardly able to pull back after an advance.  It is a little gummy,  though.

Is that normal?  Or are my advance springs stretched out?  I plan on 
cleaning and lubing the mechanisim,  as soon as I find a magic tool to 
get at that @#$@ hold down nut...  Actually its the @#$$# air pump 
bracket in the front of the engine.. gets in the way of a LOT of 
things..  I remember on the 69 Berlina,  I could just get that nut with 
a regular box end wrench.
