Carburetor
Maintenance
Should you experience difficulty with
the carburetor of your engine:
1. Check that the slotted head of the
Idle Needle Valve (89) is flush with
the throttle arm housing. This will
put the idle needle back to the factory
preadjusted position.
2. Remove the high-speed needle
(85) and flush out the spray bar with
clean fuel. Replace the high-speed
needle and follow the instructions in
the Carburetor Adjustment section.
3. Always use a high-
quality 4-cycle glow plug.
Saito SS (SAIP 400S) or Hangar 9
(tm) Four-cycle Super Plug
(HAN3011) is highly recommended.
Tips For Extended
Engine Life
To add longer life to your Saito
engine, the following
recommendations are made:
1. Use a high-quality fuel containing
20% lubricauts.
2. Use recommended glow plugs.
3. Use the proper propeller size and
balance the propeller prior to use.
4. Use a tachometer for precise
engine adjustments.
5. Use an "after-run" oil when you're
finished flying for the day. Hangar 9
After Run fuel is recommended.
6. For long-term storage, make sure
there is no fuel left in the tank and the
engine. Remove the glow plug(s) and
apply several drops of high-quality
light oil (e.g., a good quality light
machine oil or Marvel Air Tool Oil)
to the top of the engine, into the glow
plug hole, down the pushrod tubes,
and through the crankcase pressure
vent (breather nipple). Rotate the
crankshaft several times. Store the
engine in the box or on the airplane
with the nose down in order to keep
oil in the bearings.
