<VV> Adjustment of Accelerator Pump Linkage

[Mikeamauro at aol.com]

I'm looking to increase the amount of "squirt" from my carbs. To do  so, 
before enlarging the pump orifices in the carb throat, I'd like to  first try 
an accelerator pump linkage adjustment. To increase the pump stroke,  should 
I INCREASE the bend in the pump linkage? The linkage is presently set to  
the index mark. For those who care why I may want to get more accelerator 
pump  delivery, read further, below. Otherwise, can someone confirm my  
supposition as to which way to bend the pump linkage for increased raw  fuel 
delivery... Thanks!
 
My 67 110, PG tends to tip lean when accelerating quickly from an  idle. 
Consequently, there is a momentarily lag in acceleration. There is NO  lag 
when acceleration is gradual, and engine is allowed to pass the "just off"  
idle point prior to getting into the gas. To preface this conversation 1): I am 
 certain the lag is due to a lean condition, as the vehicle is equipped 
with  broadband O2 sensors (one each bank), reading to cabin mounted digital 
gages...  the reading goes, momentarily, to 17;1 AF ratio, before settling 
back to normal  range (14 to 15:1). And 2) this is not a tuning or timing  
issue... the engine is modified to a tight quench distance, which  permits 
plenty of initial timing (18-degrees BTDC, and the car is "zippy,  other than the 
lean tip), and, 2) the carburetors are in good condition and  the 
accelerator pumps are providing a good stream of raw fuel when called  upon to do so.
