<VV> Engine miss with rapid tach movement

[Dan & Synde]

Well, the engine is back together and running in the Greenbrier!  Yea!!
After a five year hiatus we are back in business.  I tried the static valve
adjustment and it works great.  Now I get to troubleshoot an ignition
problem.  The engine has an intermittant miss that appears to be an ignition
problem.  The tach needle follows the miss and occurs intermittantly at all
speeds with slight but rapid deflections.  It does it regardless of engine
temperature.  I first suspected the condenser but replaced that and the
problem still exists.  The cap and points are new "Blue Streak" parts, the
plug wires are new silicone 8mm.  The alignment on the points is good and is
gapped to around .016 inch.  The points plate is a Dale unit and I double
checked the ground wire connecting the advance plate with the distributer
body.  I checked the wiring leading from the points to the (-) coil lug and
it is good.  Shaft runout is minimal.  Voltage to (+) lead of coil is around
9V.  The coil measures good, low resistance between (-) and (+) (2-3 Ohm)
but high resistance between (+) and the coil output (9 kohm).  I'm beginning
to suspect either the coil or the points even though they test good,
sometime it's a dynamic thing.   Any ideas?
