when setting up the idle and idle in gear the power step up spring /primary rods must be down lean in the jets
at idle or the idle will be off. idle manifold vaccuum in gear. 3" or 4" step up spring should do it.
as a start.
Do not allow the engine to idle slow and "load up" when its cold.
Give it trpm while warming up. You need clean crisp spark plugs to get the throttle response
you are after. Don;t let the einge load up when its cold. RPM is your friend. while its warming up.
Please verify that the MSD is switching from cranking start- retard mode to run mode ... 36deg fixed idle timing at 500 rpm
and does not fall back down, when you go in gear.
and does not advance further with rpm.
