Glad its gonna work, Its gonna work right!?!
YES! It works.
Had today help from a friend. Mechanical advance was all in at around 1500 RPM. Changed one spring and now it is around 2100 RPM all in.
Initial advance is now set to 14°
Full advance with mechanical is 36° (without vacuum)
vacuum is now set to 4 turns counterclockwise which translates to 14°, when I actuate it with manifold vacuum, when idling.
No ping without vacuum, no ping with vacuum.
Idle screws needed another 1/4 turn richer to get a small vibration between 1000-1500 RPM fixed.
It is much better off the line, that is a big improvement for city driving.
Perhaps the last ride this year, because it is getting here cold too. But I'm really happy, that the ignition is now set and it works very well.
I also pulled one plug before I started the tuning session today, which looks also good to me:
