1 ,yep ,just pop it off (I just seen a good vid showing how to do this
)2 the screws shown are the idle mix screws and the throttle bypass screws . The idle screws should be reset as per manual ,there is no real point in recording their position now as cleaning will alter the actual fuel flow and they probly aint right anyhow. The bypass screws are to ballance the two venturies and one should be fully closed , and the other opened enough so there is equal air flow in both venturies .....so probly not a whole lot of point in recording them either , specially if you plan on removing the throttle shaft and plates. Once you have stripped and cleaned the carb its real unlikely that the before settings would remain correct after the stripping and cleaning....one would hope not otherwise why bother
