What works...

123 Tune set at 15 BTDC on it's base point...what they call "static timing"

7 deg advance at 500rpm, 9 @ 1500, 15 @ 3000, 21 @ 4000, 20 @ 5000...five points only...Maxed at 36 BTDC. 123Tune pastes in the interim points for you, as the revs climb...

Without rejetting, air/fuel ratio changed to richer mixture of 12.5 to 15 instead of 14 to 16.

Lumpy but steady idle, clean plugs, quicker revs, no stutter off the line...

Next stop...dyno team...
