8. Insert the float hinge pin and test the movement of the float up and down
and that it moves the needle up and down in the fitting. (When held upside-
down, the bottom of the float should be parallel to the casting of the valve, in
both directions). This very important to keep the float from binding on the
stem guide as it moves up and down. If the float is not parallel to the casting,
the float pin tabs on the float will need adjusting. Hold the float firmly and
bend the tabs using needle nose pliers, being gentle to not break the float
from the tabs (a small crack is acceptable). Bend both tabs down or both up
to keep the float level parallel, being careful not to put pressure on the
needle and seat when making the adjustments. Check the float for sitting
perfectly straight as you may need to bend one tab up and the other tab down
in order to achieve the bottom of the float straight in both directions.
9. Replace the top casting into the bottom casting so the metering stem slides
in to the metering guide with oil inlet on the same side as the oil overflow.
Replace the 2 top screws snugly, and move the control knob up and down
while tightening the 2 screws. Once tight, the control knob should move up
and down freely in any position.
10. Measure your fuel flow to the specifications on Pg. 27. Once you have
adjusted the flow rate, check the overflow fuel line for oil drips. If the float
is operating correctly and adjusted parallel to the casting, the oil level in the
valve will be correct. The high fire screw inserted into the high temperature
fuse can also be replaced or kept as a spare.
