OPERATING THE SPREADER
Tecumseh Choke Adjustment Procedure
1. The choke linkage and choke adjustment screw is
shipped from the factory with the choke butter fl y
set to 75% fully closed choke.
2. With the choke set at 100% the engine will not
stay running in the choked position. This position
is for
extremely cold conditions. Throttle linkage
travel from 0% to 100% choke is 3/16". Four and
one-half turns of the Choke Adjustment Screw
(clockwise when viewed from above the engine)
will take the maximum choke setting from fully
closed to fully open (no choking at all).
3. To adjust your choke setting loosen the
adjustment retainer screw and rotate the Choke
Adjustment Screw clockwise one full turn (scratch
a mark on the knob to indicate position). This will
generally allow the engine to run very roughly with
the throttle linkage at maximum choke. This is
approximately the equivalent of 75% fully closed
choke.
(This is the factory setting.)
Honda Choke Adjustment Procedure
1. Engines are shipped with choke adjusted to the
completely closed position when the choke is
engaged. The choke only requires adjusting if
inspection reveals the choke is not fully closing.
2. Move throttle control to full choke position.
3. Turn choke adjusting screw counter-clockwise fi ve
to seven turns.
4. Attempt to move choke rod in the direction of
the choke adjusting screw. If the rod has no
movement, no adjustment is necessary.
5. Return the choke adjusting screw to its original
position or clockwise until it touches choke lever.
6. If the choke rod has movement, bend engaging
tab in the direction away from choke adjusting
screw until there is no choke rod movement.
7. In the event bending the tab fails to remove all choke
rod movement, partially straighten out the bend in
the choke rod. This bend is near the governor arm.
8. The choke adjusting screw, when properly
adjusted, stops excessive force from being
exerted on the choke actuator.
4. Additional adjustments can be made by 1/4 turn
increments until you reach the desired start/run in
choke setting of your preference/need.
