berglass cutting tools and

ety equipment.
Cut one of the fi
berglass
engine
co
wls to fi
t o
v
er the engine—it doesn’t matter which
of the tw
o co
wls y
ou choose because the
y
are both
the same
. Cutting the hole is basically a tr
ial-and-error
process where y
ou cut-and-fi
t
and
cut-and-fi
t
the
co
wl
until it goes o
v
er the engine
. If using a 4-strok
e
, the
co
wl fi
tting procedure will be easier if the v
a
lv
e co
v
e
r
is tempor
ar
ily remo
v
ed.
If using a 2-strok
e
the co
wl
will be easier to fi
t if the head is tempor
ar
ily remo
v
ed.
This will allo
w the co
wl to fi
t without ha
ving to fi
naliz
e
the e
xact siz
e
, shape and location of the cutout until
after the co
wl has been per
manently mounted.
Star
t
b
y
tr
ying to fi
t the co

will go
. Use a fi
ne-point f

lt-tip pen or a lead pencil
to mar
k the inside of the co
wl in the appro
x
imate
location where the engine will stic
k out.
