Step 6
Remove the template and air funnel. Use the funnel to
complete marking the circle on the template.
Step 7
Use a hobby knife with #11 blade to cut out the
marked section of the template. Use a pencil to mark
which is the inside of the template so that it can't be
installed incorrectly.
Step 8
Align the screw holes in the template over the mount-
ing holes on the right side of the cowling and tape it in
place with low-tack tape. Use a felt-tipped pen to mark
the location of the cutout for the intake funnel.
Step 9
