Here's a cool calculator that may help in tuning. Pair this with a wideband A/F gauge and it will guide which way to go as far as jets and rods.

Calibration Kit procured!

I'll check that tool, but really, being an engineer myself and having written manuals, my opinion is the Edelbrock carb manual is really great. I'm confident it is all I will need. Gonna go make a metering rod change. Maybe it will stop raining and I can take it for a test.
