<VV> Float drop question

[James Davis]

Depends on the type of needle and seat.  If the drop is too great, 
the needle will wedge in the seat causing flooding.  All you need is 
enough drop to allow the fuel level in the carb to drop as Rochester 
intended.  Too little drop and the fuel level in the carb will get 
too low causing a lean condition at full throttle.  I find the Viton 
tipped needles most prone to lodging. Of course if you use Gross Jets 
you don't have a float drop setting problem.
