I have  read before that the Carter YH accelerator pump delivers a fuel 
squirt,  
but that this is preceeded by enrichment delivered when the vacuum drop  
causes 
the choke plate to "blink". I understood that the blink is caused  by the 
vacuum 
unloader briefly letting the choke close partially when the  vacuum level 
drops.
 
 
The blink is caused not by the unloader, but by the choke pull-off. the  
unloader is entirely mechanical.
 
 


If I  have that straight, can someone explain why there would be a blink 
even  
after fully warmed up? 
 
What makes you think that there is a choke blink after the choke fully  
opens up and is held in position by the thermostatic coil? It shouldn't happen  
as far as I know. Please explain.

I would  have thought that the unloader was no longer 
affecting the choke position  once warmed up.
again, you mean "pulloff" I think.
