<VV> 140 miss update

[Ralphsebrell]

I took Jim's advice and removed the vacuum hose and plugged it. Ran pretty good, in town and 70 mph hiway  :-)
removed the vac advance "Bell" and it holds a vacuum. The points plate rotates. When plugged in , Back to sq one. 
Distributer # 1110371   5K21  Delco

Any more thoughts?

Too much vacuum advance.  Take the vacuum line of the distributor's 
nipple and
plug the rubber hose. A golf tee or #10 bolt works fine.  
Drive the car around
fir a while and see if you have any of the surging 
symptoms.  If that fixes it
then the easy to get 1/2 of the vacuum 
advance back is to remove the hose plug
and make a "U out of a piece of 
steel wire (coat hanger size) and place it one
leg of the vacuum advance 
dash-pot next to the distributor housing.  That will
still allow some 
advance but only about 8 degrees instead of 15 degrees.

has happened on both of my 140's. The car will start to have a small "miss", on
light throtle and light load in town. And it will get progressively worse, to
the point of bucking and kicking. Marathon hi test fuel.

I just now cleaned the outside of the coil tower with brake cleaner and it
helped some, but not yet near good running. Listened to the exhaust, and both
sides I hear a "miss" ,
