Electronic Ignition for my '72
 

Just got for my '72 ElDo a
point eliminator kit from Petronix with a new coil.
Can someone point me to a link, if any, where I can learn
how to do it?
And I don't feel like buying a timer-gun,
so I'll also have to time the thing by ear.
I've never done this before so I'm anxious
about doing it myself, unless there's a good place
to learn how to do it.
That way, I might save a few bucks too.
