Assembly

When installing new parts from a carburetor
rebuild kit, inspect gaskets and compare to origi-
nal gaskets to ensure all holes are correctly
punched. Also, inspect new gaskets for any loose
fibers or particles of gasket material.
IMPORTANT:
that all parts are clean. Make sure that all replace-
ment parts match the original ones in size and
shape. Replace all gaskets, O-rings, and sealing
washers each time you assemble a carburetor.
Refer to the figure in the Disassembly procedure

for proper assembly of the carburetor.
Checking the Float
Check for correct positioning and smooth move-
ment of the float. The float controls the height of
the fuel in the float chamber and is essential to
carburetor calibration and function.
