John....
As when setting any type of SU float height, you should simply allow the
weight of the float to sit on the needle. Do not depress the spring in
the needle (note: not all needles have springs in them, anyway).
The Haynes book is somewhat confusing about where to read the height of
the float on an HIF carb. The float has a "big" and a "little" end, with
a curved "dip" between them. The correct method is to run a straight edge
across the metal base of the carb, over the "dip", gently adjusting the
tang that sits on the needle until there is a 40 thousandths gap between
the float and the straight edge at the "dip".
