Bob: with vacuum advance temporally removed and plugged, what would you say 
 the maximum advance should be for a 110 with a .032 quench distance? I'm  
presently running an initial of 18 btdc; runs well with minimal ping--lots 
of  "zip" and strong idle, but often wondered if I'm loosing cruse efficiency 
 by being too far advanced. Maybe I should keep the same initial  setting, 
but bush the mechanical stop pin for less total  advance? Thanks.
