11. Plug the smoke fi tting on the
muffl er with a segment of fuel
tubing and an 8-32 screw (not
included).
12. Cut all necessary clearance,
carburetor adjustment, cooling,
and exhaust holes in the cowl.
13. Ensure the sensor wire is supported as close to the sensor pick-
up as possible. Flight loads may cause stress and damage to the
wire where it enters the sensor body.
14. Make sure the cowl is secured to the airplane and that the
spinner to cowl clearance is at least 3.2mm [1/8"]. If starting the
engine the fi rst time and during break-in it’s recommended that
you run the engine without the cowling.
Drill and Install the Propeller
The easiest way to drill the propeller to fi t the hub is to use a drill
guide. (DLEQ0551) If you do not have a drill guide, you can use the
following method to drill your propellers.
1. Remove the cowling from the aircraft. Use the included propeller
washer to mark the centering hole in the propeller.
2. Once the location is established, use a drill press with a #5
(.2055” / 5.21mm) drill bit as a pilot hole. Once the pilot hole is
established, use a 13/32” (.406/10.31mm) drill bit to fi nish the hole.
In order to achieve a clean opening on both sides of the propeller,
drill only half way through the propeller with the fi nishing drill bit.
Then fl ip the propeller over and drill completely through the hole.
3. Next, set the engine
at the beginning of the
compression stroke. Note
the position of the ignition
magnet with engine inverted.
