Rich Idle AFR reading
@Mattax great info, thanks. My FSM show 5* btdc for factory 2bbl timing and for altitude to advance up to 5* more. So you think going back to stock timing even with my electronic ignition? I will give that a try. Also setting IMS according to rpm not total vacuum. I will do that as well.
I will set idle speed to 600-650.
I will try to map out how quickly my timing curve is. Should that be with or without the vacuum line attached? My distributor is adjustable with different springs.
I will try all of this as soon as it stops snowing!
Thanks for the help.
