well things were better but I kept going

TEST 2 - I set my Idle Mixture Screws only 1/2 a turn out

AFR Reading: this further leaned out my air fuel ratio from high 14s / low 15s (a bit too much)

RPM: this is where it gets interesting, my revolutions dropped from 700 to 600, wait a minute, last time we leaned things out and the revs went up, and this time we leaned things out some more and they dropped? yup, that's how it works, once you pass the sweet spot the carb tells you it aint happy any more
