5. Install the choke servo (optional) at least

305mm [12"] away from the engine. Be sure

to use a non-metallic linkage.

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.

6. Connect the ignition wires from ignition module to the spark plugs.

7. Install the mufﬂ ers onto the engine. Be sure to use threadlocker,

and that the ignition wires do not contact the mufﬂ ers.

8. If not being used, plug the

smoke ﬁ ttings on the mufﬂ ers

with a segment of fuel tubing and

an 8-32 screw (not included).

9. Cut all necessary clearance,

cooling, carburetor adjustment,

and exhaust holes in the cowl.

10. 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 ﬁ t the hub is to use a DLE

drill guide (DLEQ1111). 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
