Bubba, I re-read your page http://www.bubbasignition.com/timing-page-2.html
Should not the index slide be clockwise from centre for initial advance ?
Normally, if the points are set correctly, the Index slide will be one notch counter-clockwise from center ... not centered. No matter what, it needs to be set on each distributor. Each notch represents 2 distributor or 4 crankshaft degrees. This means that on an 11A distributor you can expect 22 degrees of mechanical advance PLUS 4 degrees for each notch. If you want more than 34 degrees (!) at the third notch, you can fiddle with the point gap and squeeze out a little more advance.
So are you saying if we have a timing light, 26 degrees is best ?
,,22 mechanical at crank plus 1 notch on slider for 4 at crank?
I have a 221 pilot engine with crab that does not ping to let me know anything.
No vac brake , piston is removed.
I want max low down torque, not high RPM power.
