he first thing you must remember about the M17 decon is that oil must be mixed
with its gasoline. If you forget and run just straight gas through the engine, you'll
soon need a new engine.
But fuel matters are complicat-
ed even more because the M17
uses two different engines with
two different fuel/oil mixtures. If
you use the wrong mixture, you'll
also need a new engine.
If you have M17s in your unit
with different engines, here's how
to keep the fuel/oil mixtures
straight. The JLO engines have
silver fan guards, so paint the
tops of their fuel cans silver or
white. For the JLO, mix one
quart
of oil per five gallons of
MOGAS.
The Cuyuna engines have
black fan guards, so paint the
tops of their fuel cans black. For
the Cuyuna, mix one
pint
of oil
per five gallons of MOGAS.
Mix the fuel and oil in the fuel cans
before you go to the field. But remem-
ber when it's time to use a fuel can, you
must shake it to mix the fuel and oil.
That creates pressure inside the can, so
open the lid slowly with the opening
pointing away from you. Otherwise,
you could take a MOGAS bath.
If your unit has M17s with JLO
engines, you might want to get the
JLOs replaced with Cuyunas. There are
few replacement parts in supply for the
JLO. To get a new Cuyuna engine
along with a mounting kit, order NSN
