Starting an Engine Equipped with eChoke
™
NOTE: Do not crank engine continuously for more than
10 seconds at a time. If engine does not start,
allow a 60 second cool down period between
starting attempts. Failure to follow these
guidelines can burn out starter motor.
NOTE: If engine develops suffi cient speed to disengage
starter but does not keep running (a false start),
engine rotation must be allowed to come to a
complete stop before attempting to restart
engine. If starter is engaged while fl ywheel is
rotating, starter pinion and fl ywheel ring gear
may clash, resulting in damage to starter.
1. This eChoke
™
system automatically controls choke
plate position for starting.
2. Make sure equipment is in neutral and brake is
engaged.
3. Activate starter switch. Release switch as soon as
engine starts.
4. For operation, after engine starts, move throttle and
set desired engine operating speed.
5. If engine does not start, remove air cleaner cover,
and air cleaner from air cleaner base.
6. Confi rm connection of stepper motor assembly to
carburetor.
7. With key switch set to OFF, choke plate should
nearly fully closed, stepper motor for eChoke should
be near full extension (expanded bellows).
8. With engine/ambient temperature above 40°F (4°C),
turn key switch from OFF to RUN. There should be a
noticeable movement of choke plate.
9. If no movement:
a. Shut off key switch and test for full travel of
actuator by disconnection and reconnection of
constant power (RED/GREEN STRIPE) at engine
connector.
b. If there is still no movement, separate tests to
validate battery voltage and power and ground
connection to master controller need to be
performed.
10. If movement is noted, attempt to crank and start
engine. (Do not exceed 10 seconds of cranking.)
11. If engine does not start:
Release key to RUN position, (do not shut OFF),
pause, movement of choke should be noted.
Repeat from beginning of step 10 (this routine can
be attempted 4 times). Choke should be fully
relieved after fi nal attempt. If eChoke
™
assembly
moves choke plate through each attempt, but engine
still did not start, problem is not associated with
eChoke
™
, but is rather another system or component
issue.
