Re: single vs double batch fire

[romans@starstream.net (Romans, Mark)]

Looking some bins and the air fuel mode words, working on a different
problem i have found  that (89 Code) only the 305 5 speed bin uses the
single fire mode.  All other F&Y body bins that I have looked at use double
fire mode.
