FINAL ASSEMBLY
INSTALL THE COWL & PROPELLER
❏
1. Install all engine accessories like the muffl er, needle
valve extension, throttle pushrod, and all fuel lines. If you
didn’t apply threadlocking compound to the engine mounting
bolts, do so now. Check all mounting bolts for proper torque.
Turn on your radio and do one fi nal check to see that your
throttle is rigged properly. Set your idle position per the
engine manufacturer’s specifi cation.

made while trimming the cowl. Use the six (6) 1/2" [13mm]
button head screws to attach the cowl.
❏
3. Attach a 3-1/2" [89mm] spinner (not supplied) and a
suitable propeller. Always balance your propeller (and spare
props) using a prop balancer.
