Fuel
• Mix a ratio of gasoline to oil of 20:1
for break in. After break in you can go
to a mix of 30:1.
• A mixture of commercial regular
gasoline and a reliable oil for
2-cycle engines can be used. Unleaded
high-octane gasoline is not required for
Saito engines.
• Remember to use caution in the
storage, use and transport of gasoline.
• Since commercial gasoline has
many impurities, please be sure to use
a reliable fuel filter (SAI50109) in
your fuel system.
Note:
• Be sure to use a gasoline-resistant type
of fuel tubing (like Tygon) DO NOT
use any silicon rubber type of fuel line
to the engine or in the fuel tank.
• Do not use any alcohol fuel or alcohol
added fuel (ethanol), as this will
cause damage to the rubber parts of
the carburetor.
Fuel Tank and
Plumbing
The recommended fuel tank capacity
is between 350cc–450cc. Be sure to
include a reliable fuel filter in your fuel
system. The drawing above suggests use
of a fuel feed line and an air intake line.
Also, be sure to use fuel line compatible
with gasoline.
IMPORTANT:
Air is necessary to cool
the engine during operation. Make sure
that sufficient air circulation through
the cowling is provided. As a basic
reference, the outlet area should be 3
to 5 times the area of the inlet area to
provide adequate cooling.
Ignition System
The Saito FG-36 comes with Saito’s
own ignition system composed of the
ignition unit, cord for sensor (black and

white), cord for earth to ground (green)
insulated plug cap, and cord (black and
red) for connection to a battery (not
included). You will also need to secure
an on/off switch (safety switch system)
of a capacity of more than 3 amps.
Saito recommends the use of a battery
with a voltage of 4.8V to 6V and a
capacity of more than 1,000mA.
Be sure to mount the ignition system
in a location near the engine and
away from the receiver to prevent any
unwanted interference. Please refer to
the diagram below:
Spark Plug
NGK-CM6 is the standard-equipped
plug with the engine. For replacement,
please replace with a product as reliable
as the NGK-CM6.
Carburetor
The carburetor used on the FG-36 is
exclusive to Saito and this particular
engine. Since it has a negative pressure
type fuel pump, the engine can be
mounted in any position.
