ISV internal operation question

[Chris Hall]

CAR: 1985 Coupe GT ISV part number 034 133 455 (no ending letter. 
seems to have been manufactured in 83 by the round stamp on it, plus 
has what appear to be junkyard part numbers painted on it in pink so 
probably not the original part...)

QUESTION: To check out my ISV, I pulled it from the 2 hoses, left the 
key in the "on" position so the ISV was buzzing, and looked inside.  
The little door on mine only opens up maybe no more than 1/8 of an 
inch when it's being cycled as the ignotion is on.  I was under the 
impression that the internal moving part ("door") spun 360° at various 
rates in a duty cycle type fashion.  

Also, when trying to move the spinning piece (armature I guess you'd 
call it...) with the power disconnected, it felt like it was spring 
loaded to auto return to almost shut when no power is applied to it.  
I've heard people say to "spin it" with a toothpick, etc... but this 
one definatly doesn't spin freely...   Is this CORRECT operation, or 
is mine siezed up?  I flushed the sucker with probably 1/2 of a can of 
carb cleaner and still does the same thing...
