<VV> update, and another cry for help; engine trouble

This is normal. With the engine off, and the points closed, the load of the 
coil AND the resistor in series, should show 6 volts at the coil. If the 
points were open, then you should see about 12 volts. This is ohms law.
With the engine running, you really have chopped voltage at the coil. as the 
points are opening and closing. So 10 volts is really the AVERAGE of the 
coil voltage. And this will be dwell dependant.

Hello again guys,

     Alright, got the carb filters changed and they made an improvement in 
the way the engine runs when its running ok, but didnt fix the problem.  I 
did track down what I believe to be the cause, I need you guys to give me 
the solution!

     With the key on and the engine not running I have just under 6 volts 
coming into the coil.  With the engine idleing there is just over 10 volts 
at the coil.  As far as I know this is backwards!  There should be extra 
voltage there for starting and lower voltage for running.  The coil is super 
hot, I believe overheated and therefore erratic.  This also would explain 
why replacing the coil fixed the problem for a time, then it started to fail 
again after about 8 hours of drive time, spread out over a month.

What could be wrong to give me 6 volts at the coil with the engine off, and 
10 volts with the engine running?

NOTE: PLEASE E-MAIL ME DIRECTLY WITH REPLIES, I USE DIGEST AND WOULD LIKE 
THE ANSWERS AS QUICKLY AS POSSIBLE AS I AM FIDDLING WITH THE CAR WHILE YOU 
ARE READING THIS.  thanks!
