I'm confused...and I realize it's likely just me... In the instructions for the 066 it says for the "H" screw. Turn high speed (H) Counterclockwise up to the stop," If I turn it all the way clockwise, it stops, but turning counter clockwise as it says, it never stops, it just unscrews out of the carb body. Am I reading that wrong. Do I turn both the L and H all the way to the stop, then back H off 3/4 and L off 1/4? See below grab from the 066 manual.
