Hey All,
I've been chasing down a very specific stall problem (
http://www.peachparts.com/shopforum/showthread.php?t=253042) and I was running some preliminary tests before I went full tilt into testing Duty Cycle/EHA/ICV/CPS/etc (following this article:
http://www.landiss.com/mixture.htm) and I tested:

1) Idle Contact: Deflect the air flow sensor plate. The duty cycle should decrease to 10%. If it remains at 70% test the throttle valve switch (Job 07.3-121).

I got no response from the Dwell Meter when deflecting the air flow sensor plate (big one on top of the fuel distributor, right?). Hmm. So I pulled the Throttle Valve Switch (TVS) connector and tested it as per the FSM:
(Idle Contacts = Pins 1 & 2, Full Load Contacts = Pins 2 & 3.)
These are my findings:
Idle Speed Contacts were as specified in the manual.
Full Load Contacts were showing infinite resistance at all positions (idle, Full & Partial load).
I tested & re-tested this.
Can anyone explain to me what this means?
My stall can be explained (short version) as only happening when I go "full load" (accelerate hard) and then stop abruptly. I'm assuming that an F-ed up/sticking TVS could cause this, but we all know what they say about assumptions...
I guess my main question is: Do my test results signify a faulty TVS?
I will be updating all threads related to my SSS when I finally lick this problem.
Thanks!!
