The  feeler gauge setting is only  approximate, especially with used 
points. The  dwell meter (assuming  you trust the calibration of your 
dwell meter)  reading is the one to  follow. Sometimes it's worthwhile 
to borrow another  dwell meter to  see if it reads the same as yours. I 
calibrated mine years  ago,  after it had an unrelated problem. It was 
right on, but they usually   have internal calibration pots and it's 
possible that yours has   drifted.


These were new points (that I bought from you in   Carthage). After 
Sunday's 
deal, I thought I'd replace them before heading  out to  Colorado. My old 
points had a large gap too, but the dwell  was only 45. Those  points were 
at 
least 5 years old, and were used  going to Missouri and back  (Bosch 
parts). 
I'll look around, and see  if I have another dwell meter, but the  one I'm 
using, I've had for  over 20 years now, and it really only gets used once  
or 
twice a  year, otherwise it sits in the cabinet. I might try the spare   
distributor that I carry for road trips, just to make sure things are  
working  
correctly.



Well, after doing a little reading thru Bentley, I found that opening the  
points, drops the dwell. Anyway, I did swap over to my spare distributor, as 
I  found that the vacuum can on the old one wouldn't hold vacuum. After 
installing  the spare, and setting the timing, WOW, what a difference. It 
really woke the  car up. It started up very easily, and runs smooth from idle all 
the way up to  3500 rpms. I did check the dwell on it too, and found it to 
be 58 (which  according to Bentley is ok for a used set of points, which it 
has). The idle  speed is a little higher than I'd like (about 875), but it's 
so smooth that I  think I'll leave it alone. Now I can concentrate on 
getting the rest of the car  ready to go to Colorado (finishing up some minor 
stuff, packing tools and  spares, that sort of stuff).
 
I did try the other dwell meter I have here, and found it to be off, as it  
was reading 42 (versus my normal meter's 58). I think the older unit is 
probably  pretty close, but if you split the difference of the readings between 
the 2,  then you end up with 50. ;-)
