Step 11 Gas Engine Preparation
Remove and keep the four M4x14 Phillips head screws
to remove the pull start unit from the factory mount
plate. Similarly remove the factory pull start plate and
also keep the M5x14 flat head screws. The screw will
be reused to mount the engine and pull start unit to
the helicopter.
Care must be taken in removing the M5 flat head screws
from the engine because they are very tight. Use the
T-handle Phillips screwdriver tool that is included with
the engine, as this it the correct size.
Step 12 Landing Gear Frame
Align the engine crankcase to the land-
ing gear frame and carefully route the
red coil wire above the coil without
putting a strain on the wire. Insert three
M5x15 countersunk Phillips screws
using L242 Blue threadlock. On some
helicopters, the clutch will sit slightly
below the bottom of the clutchbell. If
needed, insert three shims between the
engine and the landing gear frame.

Install the spacers onto the M4 socket
bolts. Install two M4x6 socket bolts
with spacers to the rearmost holes us-
ing L242 Blue threadlock. These only
hold the plate while starting, do not
overtighen. Install the M4x10 socket
bolts with spacers to the forwardmost
holes using threadlock. Using the
original M4x14 Phillips bolts, insert
the screws through the removable plate
with the larger end of the keyholes in
the counter clockwise direction. Mate
the pull start unit from the other side
with the handle down and rearward and
secure with four M4 locknuts. This will
position the handle on the carburetor
side with space to pull freely.
