7-7. Adjusting Engine Speed
If the engine does not start and stop properly, verify the fuel solenoid is installed
properly before adjusting engine speed (see Section A following).
If the engine does not stay at idle speed, verify the throttle solenoid is installed and
adjusted properly before adjusting engine speed (see Section B following).
If the engine runs properly but the speeds are incorrect, do not adjust the
solenoids. Adjust the engine speed according to the instructions in Section C.
NOTE
A. Checking Fuel Solenoid
Ref. ST-801 961 / ST-802 649
Y Stop engine.
If the engine does not start and stop when
using the Engine Control switch, check
the position of the fuel solenoid.
Adjusting Fuel Solenoid Position
1 Fuel Solenoid
2 Stop Screw
3 Fuel Solenoid Mounting Screws
. Stop screw is factory-set and should
not be adjusted.
When properly adjusted, the solenoid
bracket is slightly recessed from the edge
of the engine block and the solenoid link-
age easily travels between the stop screw
and the fuel solenoid internal stop.
If adjustment is necessary, loosen the so-
lenoid mounting screws and push the so-
lenoid bracket back toward engine as far
as possible.
Continue pushing on solenoid bracket in
a clockwise direction while tightening
mounting screws.
4 Shutdown Lever
5 Stop screw
6 Stop Screw Jam Nut
7 Fuel Solenoid Jam Nut
8 Plunger
. Stop screw is factory-set and should
not be adjusted.
Hold throttle solenoid in idle (energized)
position. If shutdown lever is touching or
within 1/16 in of stop screw, fuel solenoid
is properly adjusted.
If lever is more than 1/16 in. from stop
screw, check for clearance between jam
nut and fuel solenoid. If there is clearance
between jam nut and solenoid, loosen nut
and turn plunger clockwise until lever
touches stop screw. Retighten nut.
If there is no clearance between jam nut
and solenoid, loosen the solenoid mount-
ing screws and reposition the solenoid as
described at the beginning of this section.
Tools Needed:
Verify mounting
bracket is recessed
from edge of engine.
