Now that the choke pivot arm is removed, use a vise to secure the
pivot pin so the peened choke arm can be removed. Next reinstall
the choke pivot arm on the carburetor making sure to reinstall the
ball in the pivot pocket and properly reinstall the choke fl ap. Secure
the lower profi le of the two included arms to the choke pivot pin.
Use both set screws and thread locker to secure the choke arm.
Install a ball link and lock washers to the choke arm (available at
your local hobby shop). Next, install the linkage from the servo to
the choke arm.
7.
Connect the ignition wires from ignition module to the spark plugs.
8.
Install the muffl ers onto the engine. Be sure to use threadlocker,
and that the ignition wires do not contact the muffl ers.
9.
Cut all necessary clearance, cooling, carburetor adjustment, and
exhaust holes in the cowl.
10.
Please 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.
11.
Make sure the cowl is secured to the airplane and that the spinner
back plate to cowl clearance is at least 1/8" [3.2mm]. When starting
the engine for the fi rst time and during break-in, it’s recommended
that you run the engine without the cowling.
Drilling the Propeller
The easiest way to drill the propeller to precisely 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. Most propellers
within the recommended size range have a 0.393" [10mm] center
hole pre-drilled. If your propeller has this predrilled hole, move on
to step 3. If not, start with step 1.
1
. Remove the cowling from the aircraft. Use the included propeller
washer to mark the centering hole on 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.
