Starting the Engine

Caution: There is always the possibility of the

propeller flying off if the propeller nut loosens due

to detonation or "kick-back" when the engine is run

too lean or is under a heavy load. This is especially

true of four-stroke engines and can be very

hazardous. Saito has provided a prop nut/anti-

loosing nut with the engine and they should be used

to prevent the propeller from flying off, even if the

propeller should loosen.

1. The propeller center hole should be reamed to the

propeller diameter. Be sure the propeller is balanced.

2. Mount the propeller to the crankshaft.

3. Fit the propeller washer and nut to the propeller and

screw them onto the crankshaft. Tighten securely with

the wrench provided.

4. Thread the anti-loosening nut onto the crankshaft.

Tighten firmly (but excessive force is not necessary)

with the wrench provided.

Crankshaft and prop nut/anti-loosening nut and

prop washer.

5. Make sure the fuel tank line is properly connected.

The fuel pick-up line should be connected to the

fuel inlet nipple and the vent line should be

connected to the pressure nipple on the muffler

pipe or flexible muffler (optional).

Muffler attached to engine and lines running to tank

6. Fill the Fuel tank.

7. Prime the engine.

a. Check to make sure the glow plugs are

not connected to the heat source (glow plug

clip/locking socket).

b. Open throttle fully.

c. Rotate the propeller in a counter-clockwise

direction 2-3 times while plugging the ends of

the mufflers with your fingers so as to draw fuel

into the carburetor.

Electric Start

Note: When using an electric starter (12V), care

should be taken to be sure the engine does not

become "hydro-locked" (flooded with fuel). While

the electric starter will turn the engine over, it may

damage the connecting rod or other components, If

the engine becomes hydro-locked, simply remove

the glow plug(s) and turn the engine over a few

times (without glow driver attached) slowly by

hand. The excess fuel will be forced to exit the

engine via the cylinder head.

1. Move the throttle arm to

/4-

/2 open position

using the transmitter throttle stick.

2. Turn the high-speed needle valve 4-5 turns open

from fully closed.

Note: The FA-200Ti/100Ti utilizes a remote

high-speed needle valve to provide for safer

operation.

3. Rotate propeller clockwise until it is against the

compression stroke.

4. Connect the heating source to the rear two glow

plugs.

Note: It is not necessary to ignite all four glow

plugs in the dual plugged cylinder head Saito

engines. It's only necessary to apply heat to one

plug in each cylinder. The other glow plugs will

ignite once the engine reaches operating

tempereture.

5. Apply the electric starter after making sure that the

battery leads are properly connected for counter-

clockwise rotation.

6. Spin the propeller until the engine is running.

7. Allow the engine to run a few moments at the starting

high-speed needle valve setting, then slowly move the

throttle (of transmitter) to the fully open position. If

the engine slows down because it is running rich,

close the high-speed needle valve (leaning it out)

slightly until the engine runs smoothly with

a rich setting.
