Step 20
Use side cutters to remove the excess pushrod wire that
could interfere with the operation of your engine.
Note
: Use threadlock on the screw to
prevent it from vibrating loose in flight.
Step 21
Use cardstock to make a template that fits over your
particular engine. The template should allow for clearance
of the engine head, muffler, carburetor and any other items
that might protrude outside the cowl.
Step 22
Slide the cowling onto the fuselage. Use four 4-40 x
3/8-inch socket head screws and four #4 washers to
secure the cowling to the fuselage. Use a felt-tipped pen
to trace the outline from the template onto the cowl.
Step 23
Use hobby scissors and a rottary tool with a sanding drum
to trim the cowl. It is better to remove as little material
from the cowl as possible, then fit the cowl over the
engine to finalize the trimming process.
