2. Slide the cowl over the fuselage, centering the cowl
with the engine/motor prop fl ange. On one of the pieces of
tape you marked, measure forward 2" [51mm] and make a
mark on the cowl. Double check that the cowl is centered
with the engine/motor and then drill a 1/16" [1.6mm] hole
through the cowl and the cowl mounting block. Secure the
cowl with a 5/64" x 1/2" [2mm x 12mm] washer head screw.
Re-center the cowl and follow the same procedure for each
of the remaining three mounting blocks, re-centering the cowl
for each mounting block.

3. Remove the cowl. Apply a couple drops of thin CA into
the holes in the cowl mounting blocks to harden the threads.
Allow the glue to fully cure before re-installing the screws.

4. Re-install the carburetor to the engine. Slide the cowl
over the engine, marking where the carburetor makes contact
with the cowl. Carefully cut away small portions of the cowl
to make clearance for the carburetor and any other portions
of the engine that make contact with the cowl. Be sure to cut
the hole for the glow plug.
❏
5. After you have made all of the required clearances
remove the cowl, install the muffl er and then cut the cowl to
make clearance for the muffl er. If you removed the carb during
these steps, reinstall it and reconnect the throttle linkage.
