twisting and turning the Idle Mixture screws and the Idle Speed screw is a bit of an art and a science as one may and does effect the other

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

AFR Reading: this improved my ratio from 10.6 to 11.6

RPM: this raised my revolutions from 700 to 900

ok, cool, now what?

well the engine was now idling a bit too high (for my taste anyway) so we dropped it using the Idle Speed screw back down to 700 RPM, noting that the AFR stayed the same
