
Step 14a
Slide the plywood pushrod guide on the throttle pushrod.
Position the guide so it is placed as shown in the photo. Do
not glue the guide at this time.

Step 15
Turn on the transmitter and receiver. Center the throttle stick
and trim. Install the servo horn parallel to the servo center line
as shown. This will provide equal travel from low to full throttle.

Step 16
Use the transmitter to move the servo to low throttle.
Close the carburetor on the engine and use a 3mm x 3mm
setscrew and 1.5mm hex wrench (included) to secure the
pushrod to the pushrod connector.

Step 17
Use the transmitter to check that the carburetor will fully
open. You may need to fine-tune the endpoints at the radio if
it doesn't open fully, or if the servo binds at full throttle.
