<VV> Sparking Questions

[Eric S. Eberhard]

I have Pertronix II and Flamethrower II coil and MSD 6a on my Spyder and 
Judson cars.  I found several things:
         1) Starts better and runs better cold
         2) Allows be to run richer without fouling plugs

After the install I noticed number 1 right away and no other benefit.  Both 
cars I had always run a little rich (to keep things cool) and they always 
fouled plugs fairly rapidly.  I was able to increase the jet sizes with the 
MSD in place -- and with the extra fuel I could advance the timing a bit (2 
degrees on Spyder and 6(!) on the Judson car) without knocking ....

What I am trying to say is that just installing it will only do #1, #2 can 
be achieved with fiddling.

It is easy to install -- instructions have a section for the 
Pertronix!  The tach worked fine the first time but it is not obvious from 
the instructions where the wire goes.  It does NOT go on the coil ... it 
goes to the MSD wire where the other coil wire goes.

I installed mine using the same leads as usually go on the coil (round 
hole) and used screws to make the connections.  Why?  Because if the MSD 
ever fails I remove two screws and put the Petronix wires back on the coil 
and voila, I am ready to go w/out the MSD.  I installed mine in the driver 
side fender:

Both cars have one "bug" from the MSD -- every once in a blue moon the car 
will not turn off.  I turn the ignition off and it keeps on running.  I 
have read about this problem on all sorts of cars with MSD.  Usually I just 
stall the car to kill it.  I have experimented ... if I just drive it then 
try again it also goes off.  The charge light comes on indicating it is 
running from battery.  Anyone with a clue as to what this is and how to 
fix?  It is not important enough to be a big issue, it has happened 3 times 
in a year (1 on Spyder, 2 on Sedan) and I drive the Sedan almost daily.
