This carburetor uses a dampening spring on the float.
The short leg hooks onto the carburetor body and the
longer end points towards the choke end.
Install the throttle shaft and shutter. The scribe mark on
the shutter is in the twelve oclock position. Any other
position may cause the throttle to stick. Use a new
throttle shutter screw to insure that the screw does not
come loose during running. A new dust seal should also
be used on the throttle shaft.
Place the primer bulb with the retainer ring into a 3/4'
deep reach socket. Press down until seated. NOTE: An
improper seat will cause poor priming.
Install a new bowl O ring. Place the bowl onto the
carburetor with the flat area of the bowl over the hinge
pin and running parallel to the hinge pin. Insert the bowl
nut with the fiber washer between the bowl and the nut.
Remember this is a left handed bowl nut.

All Tecumseh carburetors with an adjustable float
require the correct float height to achieve the proper
operation and easy engine starts. To check the float
setting, hold the carburetor in an upside down position.
Remove the bowl nut, float bowl, and "O" ring. Place an
11/64" diameter drill bit across the top of the carburetor
casting on the opposite side and parallel to the float
hinge pin. The float must just touch the drill bit when the
bit is flush with the edge of the float. If the float is too
high or too low, adjust the height by bending the tab
accordingly. If the required adjustment is minor, the tab
adjustment may be made without removing the float and
carefully inserting a small bladed screwdriver to bend
the tab.
