When using a fuel controller

[Livingmylife93]

The old Dobeck style ones, where you adjust it yourself with the knobs or buttons on it... How exactly do you know when you have enough fuel for the RPM range? Do you just guess, or what?

yup.... just guessing till u put it on a dyno and see what it is doing...

guessing, riding and plug checking, til you get a dyno run. I did mine old school, and it works well.
