8. Once the throttle servo is installed it’s a good idea to deactivate the throttle return
spring with a pair of needle nose pliers. Gently grab the spring and remove it from
tension on the throttle lever. Deactivating the spring will remove the load or stress on the
throttle servo.
9. Install the choke servo (optional) at the same distance as the throttle servo from the
engine. Be sure to use a non-metallic linkage and a Faslink to secure the throttle linkage
to the servo.
10. Connect the ignition wire from the ignition module to the spark plug.
11. Install the muffler onto the engine. Be sure to use threadlocker and that the ignition
wire does not contact the muffler.
12. Cut all necessary clearance, carburetor adjustment, cooling, and exhaust holes in the
cowl. A 1:3 ratio of airflow intake area to airflow exhaust area is recommended for proper
engine cooling.
13. Make sure the cowl is secured to the airplane and that the knurled thrust washer
protrudes from the cowl by at least 3.4mm [1/8”].
