FLOAT ADJUSTING PROCEDURE

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" (4.369 mm) 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.
