<VV> Straws and Lifters

[Padgett]

Was just playing with the idle again tonight and went through a period 
where it would be at 600 in D, then drop to 350, then come back to 600 and 
cycle like that for a while. Juggling the mixture has no discernable 
effect. Change with Pertronix is that it does not stall at 350, just keeps 
running.

Incidently I ran some tests and the Ignitor II with .6 ohm Coil is pulling
   .7a  -  700 rpm
   .9   - 1000
1.3   - 1500
1.7   - 2000
2.0   - 2500 (end of scale on dwell/tach)
so expect it would peak at 4 amps at 5000 rpm with about 3a at 3500 (70 
mph). Talked with Pertronix and they feel the stock 18 gauge wiring is 
adequate for mild street use and this test seems to corroberate.

What I am now wondering is that while there are no additional sounds if the 
noisy idler is eliminated when it drops from 600 to 350  is it possible 
that one or more lifters stop opening valves at low rpm ? Valves were 
adjusted quite a bit tighter when I bought the car. Everything comes right 
back given a little throttle. Are now adjusted at 1/4 turn from clack warm. 
Am tempted to add another 1/4 turn across the board and see if anything 
happens but thought I would ask if am just grasping at straws.
