I ran the biondo air on-air off inline linkage stop for years on a terminator. Had very good sucess was consistent and we went rounds every divisional and national we went to. Best advice I got was to go out at least .5 on timer 1 to burn off the extra fuel from being up on the 2 step before going on the stop. Used to run 2500 stop rpm so you basically shut it all the way down so it will bypass fuel properly.
