4. With the engine in place, install the remaining two 4mm
x 25mm machine screws, 4mm lock washers, and 4mm nuts
in place at the front of the engine mount as shown in the
photograph. Do not tighten the screws at this time to allow
for the positioning of the engine.
❍
5. Install the spinner backplate, propeller, propeller washer
and the propeller nut onto the engine. Turn the propeller
clockwise until it is against the smallest pins on the backplate.
Keep the propeller horizontal when the engine is against its
compression (the point at which you feel resistance when you
turn the crankshaft counterclockwise). Use an adjustable
wrench to securely tighten the propeller nut.
❍
6. Measure the distance from the spinner backplate to the
firewall. It should be 5-1/2" [140mm] on both sides of the
spinner backplate. Adjust the engine if needed and tighten the
screws evenly, using Threadlocker on the screws and the nuts
to secure the engine to the mount. Following the engine
manufacturer’s instructions, install the muffler to the engine.
❍
7. Attach the fuel lines to the engine. The line you marked
“Vent” should be attached to the muffler. The other line will
be attached to the needle valve. Make sure there are no
sharp bends in the lines. If so, carefully shorten the lines to
allow for a smooth flowing bend to the appropriate fitting of
the engine.
❍
8. Attach the spinner cone with the screws provided. Be
careful not to overtighten these screws. They are threaded
into plastic that can strip out if they are overtightened.
