One of the most critical adjustments on the Animal PZ carburetor is the float.
The first adjustment to make is the FLOAT DROP. This done holding the carb right
side up and measuring how far the bottom of the float is from the gasket surface
(gasket removed) You make this adjustment to keep the float needle from dropping
so far out of the seat that it binds. If the needle binds the carb will over flow.
The FLOAT DROP side of the gauge is PRESET at the proper amount. The
adjustment is made by removing the float and bending the metal tab that hits on one
of the pegs that holds the hinge pin (see picture below)
FLOAT LEVEL is responsible for controlling how much fuel is maintained in the float
bowl. There are many different theories on what it should be set to. I have heard
numbers anywhere from .820" to .875" THEREFORE,THE FLOAT LEVEL SIDE OF
THE GAUGE IS ADJUSTABLE. YOU CAN SET IT TO WHAT EVER YOU WANT.
The FLOAT LEVEL adjustment is made by turning the carb upside down and
bending the tab that rests on the float needle.
See picture below.
Due to inconsistencies in carburetors it's best to measure the actual amount of fuel
in the float bowl and adjust the float level accordingly. The graduated cylinder along
with the float gauge allows you to very accurately measure the actual fuel level in
the float bowl and adjust accordingly.
The hydrometer gives you the added dimension of being able to test your fuel for
legality and best performance.
A must have for serious racers.
