Before going on a mission, make sure the engine spark plug gap is
between .035 and .040 inch (.020 to .035 inch for the M17/M17A1)
with your gap gauge. If
the gap is wider, you'll
have trouble starting. If
the gap is too wide, gen-
tly bend the electrodes
down until the gauge fits
snugly between the elec-
trodes. If the gap is too
small, use your flat-tip
screwdriver to gently pry
open the gap. Then
check the gap for the
correct clearnace. If you
have the new wire gap
setting
tool,
NSN
has a notched blade for
adjusting the gap.

If you have trouble
starting the M17, take
off the air filter. That
lets the decon suck in
more air, which some-
times is enough to get it
started. Put the air filter
back on as soon as it
does start. Starting is
easier when you keep the
air filter clean, too.
Every six months we
clean the filter with dry
cleaning solvent.
•
Tie off the burner fuel
hose to the frame so it
doesn't stick out far
enough to hit the flywheel
belt. The belt will cut a
hole in the hose and the
hose will leak. Then
you've got a fire hazard.
•
If fuel comes out the exhaust, don't panic. Sometimes the M17 gets too
much fuel in the engine during startup and it's blown out the exhaust. After
running 30 minutes, your M17 should stop blowing out fuel. If it doesn't
stop, then it's time to tell your repairman.

Dear Editor,
Through trial and error, every chemical company learns the tricks of
getting the most out of their M17 decons. These are our secrets for suc-
cessful deconning:
•
Heavy carbon buildup
in the igniter tube can
ground out the spark
plug and burn out the
igniter. Then you can't
decon until the igniter
is replaced. To avoid
that, take apart the
igniter tube every six
months and clean out
all the carbon with a
wire brush.
