4. Also cut a rounded notch in the middle of the bottom
of the cowl for the nose gear wire.
❏
5. If you will
not
be cutting a slot through the cowl from
the engine head to the back of the cowl, remove the engine
head. Insert tissue into all engine openings including the
exhaust, carburetor and cylinder (if you’ve removed the
head). Also remove the needle valve.
❏
6. Make your first attempt to install the cowl – it may not
even go all the way on yet, but get it as far as you can, then
mark where the cowl needs more cutting to fit.
❏
7. Remove the cowl, cut, test fit, mark and cut as
necessary until you can at least get the cowl over the engine.
❏
8. Once you can get the cowl over the engine, fit the
spinner onto the crank shaft and see where the cowl needs
more cutting to align – eventually you’ll need to cut the hole
for the carburetor, then finally cut for the little vertical “rib”
on the carburetor.
❏
9. Once you can get the cowl to fit well and align with
the spinner, it’s time to fasten the cowl to the fuselage.
Remove the cowl. Use a fine-point felt-tip pen to draw a
vertical line on both sides of the fuselage 1" [25mm] aft of
the middle of the firewall.
