so your thinking the bypass holes in the choke tower should NOT be blocked off? also, on the 22 degree mixture screws, do you know why those are better to use than the others?
No! They should be as this was to lean out the carb for the emissions years. This is for both holes (baseplate) demonsizzler told you to fix/adjust.
The 22* vs 12*. The angles are hugely different and the sharper point on the 22* offers a finer adjustment over the more course and quickly radical adjustments of the 12*.
