<VV> Choke & Fast Idle Adjustments (was: ambient???????)

[Mikeamauro at aol.com]

"...If the engine stalls when started, then you need to adjust the  choke 
rods a bit longer to increase spring tension and keep the choke plates  more 
closed with air flowing past them..." 
 
No disagreement with the above, but have this to add. If the choke  rods 
are already adjusted sufficiently to pull the choke plates fully closed  (with 
engine off, after tapping the gas petal), and the engine still stalls,  
then a look at the fast idle adjustment is indicated (tang on throttle lever  
needs to be on the second step of fast idle cam, with .075 clearance between  
idle stop screw and the throttle level). If stalling persists, and the 
carbs and  all else are known to be "good," it is sometimes helpful to 
straighten the choke  pull-off linkage, slightly (don't over do it), to allow the 
choke plates to  stay closed a bit more than the setting shown in the shop 
manual (this  also gives the fast idle cam a bit more "authority").
 
My wife constantly complained about 110 67 PG 110 stalling on cold  start 
up. I followed the procedure detailed above... no more  stalling.
