Fuel; Fuel Tank And Plumbing - Saito FG-14C Owner's Operating Instruction Manual

Fuel

• Mix a ratio of gasoline to oil of 20:1 for break-in and
continuous operation on all engines.
• A mixture of high-quality 91 octane unleaded
gasoline and a reliable, high-quality 100% synthetic
oil for 2-cycle engines must be used. We recommend
Evolution Oil (EVOX1001Q).
With the use of an oil mixture of 20:1, it is normal to
see a slight amount of carbon buildup on the exhaust
valve itself. This is why it is important that you use a
high-quality synthetic oil instead of standard 2-stroke
oil you may be using in your 2-stroke gas engine.
Although these 2-stroke oils work well in their intended
applications, they can cause a build up of a gummy
residue on the exhaust valve in a 4-stroke gas engine.
This may require service for your engine if the exhaust
valve begins to stick and not seal properly.
The high-quality Evolution oil we recommend will still
build up a slight amount of carbon, but we have found
that this build up is easily flaked off during normal
operation of the engine. It will not create the typical
gummy build up.

• 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
or HAN143) in your fuel system.
• The recommended fuel tubing is Evolution
Fuel Tubing (EVOA102). DO NOT use a silicone
rubber fuel line for the engine, the fuel tank, or your
fueling system.
• The use of fuel with up to 10% ethanol has been
tested and found to work fine.
• The use of a filtered clunk or sintered clunk on the
fuel pick up line is required. The Evolution In-tank
Felt Filter/Clunk (EVOA106) is designed specifically
for gas engine operation.

Be sure to include a reliable fuel filter in
your fuel system. The drawing to the left
suggests the use of a fuel feed line and
an air intake line. Also, be sure to use a
fuel line that is compatible with gasoline.
