   I don't have a carb or manual in front of me, but you do not need to 
be playing with the idle stop screw.  Put it back where you found it.  
Lucky for you, you have a mirror image carb on the other side.  Use the 
other carb to trouble shoot by comparison. 
   Have you tried to adjust the flap?  The three bolts on the electric 
choke cover can be loosened and the angle and timing of choke operation 
manipulated.  You don't need to run the engine, just turn on the 
ignition and occasionally blip the throttle cable.  Compare left and 
right.  If you can't get it to move pull off the electric element cover 
and look for something amiss.  Compare left to right.  There are alot of 
linkages in there, don't worry about the adjustment of them, just make 
sure they are not impeding the flap movement.  All that stuff in there 
is just the fine tuning of idle speed for warm-up, not necessarily for 
choke flap operation.
   Find a Haynes manual for carb info, or out of print Elfrink, maybe 
even Clymer.  Also, check out the whole carb adjustment shebang on 
Everett's site:
