Okay, I did ask for corrections, and Corvairily and technically, Frank 
is correct, and under the idea of being careful of how we state things, 
I was not,  easily demonstrating why we need to be careful about how we 
say what we post  -- VV is such a great place for finding your humility

Although the automotive ignition coil is is a simple device 
mechanically, it is not so simple electrically.  Is it a capacitor / 
condenser?  Is it an inductive choke? A reluctor?  Is it a DC flyback or 
a step-up transformer?   The answer is, in the most general of terms, 
"Yes, all of the above."  But, if you don't think of it as a  storage 
capacitor, let me 'hook you up' with an introduction to the Ford Model A 
coil  <he  he>  Frank should remember these -- a truly 'shocking' 
Halloween experience [prank] back from the days of outhouses.

If anyone is interested, a good introductory technical explanation of 
the stock automotive ignition system in your Corvair can be found here, 
completely illustrated --

On another tach <te he>, the mechanical tach in the 356 (non-Corvair) 
fortunately does not lie above the radio. The tach drives off the oil 
pump, and if the seal goes bad it doesn't take long to fill the tach 
with engine oil (about 100 miles, actually) -- takes a lot longer to 
drain back out ...
