o
6 . Tack glue the dummy engine into the cowl . Place
the cowl onto the fuselage and make sure it centers
with the engine crankshaft . Adjust the dummy engine
as needed . Pay careful attention to the clearance
of the dummy cylinder where it sits in front of the
engine . You may need to remove additional material
from the back of the dummy engine to get clearance
for the engine . Once you are satisfied with the fit,
permanently glue the dummy engine to the cowl . A
mixture of 6-minute epoxy and micro balloons works
well for this .
o
7 . Position the cowl over the engine and onto the
fuselage . Check to make sure the dummy engine
clears the engine . If necessary trim the dummy
engine to get clearance for the engine . Center the
cowl on the engine and slide it back onto the fuselage
and the cowl mounting blocks .
o
8 . From behind the cowl, the cowl mounting blocks
are visible . With the cowl properly positioned, drill a
1/16" [1 .6mm] hole through the cowl and into one
mounting block . The hole should be approximately
½" [13mm] back from the trailing edge of the cowl .
Install a #2 x 3/8" [10mm] screw to hold the cowl in
place . (When you are mounting the cowl, #2 washers
should also be used . But since we will be removing
and installing the cowl several times, don’t worry
about the washers now .) Do this for each of the five
remaining mounting blocks . Check the position of the
cowl each time before you drill .
o
9 . After you have installed the cowl, remove the
cowl . Apply a couple drops of thin CA into the holes
to harden the threads .
o
10 . For our installation we used a 90 degree
exhaust header (OSMG2624) in conjunction with
the stock muffler . This allows you to divert the
muffler under the fuselage rather than out the side
of the cowl .
o
11 . Assemble the muffler and header to position
the muffler where you want it to exit the cowl . Be
sure to use thread locker to assure everything stays
tight . When you are satisfied, install the pressure
line to the muffler .
