"There are several different float settings depending on which
type of 
carburetter/float set up you have. Listed below are the most common
options.

T1 (1 7/8b OD) and T2 (2 1/4" OD) Float chambers. With the float
chamber lid inverted and the hinge lever resting on the float needle, it
should 
be possible to just slide a 7/16b diameter between the radius of the
hinge lever 
and the face of the float chamber lid. 
T4 (3b OD). A 5/8b
test bar should be used. Early HS carburetters with brass floats. A 5/16b
test 
bar should be used.
HS carbs with the early nylon float and steel
needle. 
The gap between the lever and the face of the lid should be between
0.125b and 
0.187b.
HS carbs with the later all nylon float and delrin
type needle. 
The gap between the float and the lid face should be between
0.062b and 0.187b 
with the float resting on the needle but not depressing
it. This type is non 
adjustable."
