when I advance it to where it wants/needs to be for base timing, it then has too much mech advance. can get up to 13" vac in N with 10" vac in gear.

so dail it back to where it is correct on total advance with a low base setting for 10" vac in N and 7" vac in gear and have a fair WOT it feels like it is holding back as it builds RPM. drops of vac reading, sluggish, retarded low on power.

this is "JUST" enough vac signal to keep the lightest step-up springs down on idle.

not going to try calibrating the 1407 with a 60$ kit cause with out the advance curve correct there is no use in it.

so it at a spot I can live with.
