Optimizing hot spark

[geezer101]

I don't run numbers. I try to dynamically tune the ignition by holding the rpms @ 2k and swing the distributor 'til I hit the sweet spot and bump it back a tiny bit. Some engines are more sensitive than others when it comes to ign tuning.

Do you have a little write up on how you do it? Disconnect vacuum, hold at 2000rpm, and adjust distributor until max rpm/smoothness is obtained? I've certainly done it at idle with a vacuum gauge when timing marks were off, but never off idle speed.
