Short Silencer Choke Settings
(Pitts Style)
1) Using the throttle stick, close the choke
until it closes completely. Wait until the LED
blinks once, indicating the ignition has
memorized the “closed choke” position.
2) Using the throttle stick, open the choke
valve until it is all the way open.
Wait until the LED blinks once, indicat-
ing the ignition unit has memorized
the “choke open” position.
3) Move the choke to the closed position and
hold there for an additional 5 seconds; the
LED will blink slowly, indicating that the Short
Silencer Pre-ignition program has been set.
4) Disconnect the receiver.

until it closes completely. Wait until the
LED blinks once, indicating the ignition has
memorized the “closed choke” position.
2) Using the throttle stick, open the choke
valve until it is all the way open.
Wait until the LED blinks once, indicat-
ing the ignition unit has memorized
the “choke open” position.
3) Leave the choke open for an additional 5
seconds, and the LED will blink rapidly,

Ignition Unit Wiring
The Evolution 152GX ignition system has an incorporated automatic choke feature. The automatic choke feature will require the installation
of a choke servo connected to the choke lever via pushrod. The choke lever is not drilled to accommodate hardware from the factory but it is
simple to drill and add a ball link to the lever.
Programming of the automatic choke feature is required through a simple process. Look to the programming chart for the wiring and
programming process. There is a slightly different program procedure, depending on what type of exhaust system is installed on the engine.
If the automatic choke feature is not desired, omit the ignition programming steps and use a manual choke mechanism. The ignition
programming LED can still be used as an onboard ignition battery pack status light.
