SAFETY INSTRUCTIONS AND WARNINGS ABOUT YOUR O.S. ENGINE WARNINGS Never touch, or allow any object to come into contact with, the rotating propeller and do not crouch over the engine when it is running. Remember that your engine is not a " toy ", but a highly efficient internal-combustion machine whose power is capable of harming you, or others, if it is misused or abused. As owner, you, alone, are responsible for the safe operation of your engine, so act with discretion and care at all times.

NOTES Use an electric starter for this engine. The wearing of safety glasses is also strongly recommended. Take care that the glow plug clip or battery leads do not come into contact with the propeller. Also check the linkage to the throttle arm. A disconnected linkage could also foul the propeller. After starting the engine, carry out any needle-valve readjustments from a safe position behind the rotating propeller. Stop the engine before attempting to make other adjustments to the carburetor.

INSTALLATION Needle-valve extension It is essential that the firewall is strong and rigid (e.g. at least 15mm thick) and firmly integrated with the structure of the aircraft. The needle-valve with this engine is designed to incorporate an extension so that, when the engine is enclosed within the fuselage, the needle-valve may be adjusted from the outside. An L-shaped rod, of 1.6-1.8mm dia.
PAGE 6
Carburetor PROPELLER The needle-valve and throttle lever locations are interchangeable by reversing the carburetor. This can be done as follows: Remove the carburetor carefully by unscrewing the two screws which secure both carburetor and choke valve. After reversing the carburetor, re-insert it into the intake manifold, taking care not to damage the O-ring in the manifold. The choice of propeller depends on the design and weight of the aircraft and on the type of flying in which you will be engaged.

GLOWPLUGS The FT-160 is supplied with an O.S. Type F glowplug, specially designed for O.S. four-stroke engines. When to replace the glowplug Apart from when actually burned out, a plug may need to be replaced because it no longer delivers its best performance, such as when: Filament surface has roughened and turned white. The role of the glowplug With a glowplug engine, ignition is initiated by the application of a 1.5-volt power source.
PAGE 8
Glowplug leads The plug leads are fitted with special snap-on connectors that ensure firm contact with O.S. plug. They are a "click" fit and are not suitable for use with most other makes of glowplug. If glowplug leads are extended together as a single cable, use heavier wire, e.g. 2.0 mm 2 multi-strand copper core as supplied for earth lead. 2.0mm 2 The earth (ground) lead is fitted with a plug terminal which should be connected to the engine by means of one of the mounting screws.

2. Make sure that glowplugs are not connected to the battery. Do not heat the glowplugs while priming. (Fig.15). If very strong compression is felt when trying to turn the propeller counter-clockwise, too much fuel has been drawn into the engine. In this case, do not use force, but release the choke valve and turn the propeller clockwise slowly to eject excess fuel through exhaust pipes. Do not connect the battery to the glowplugs while priming. Fig.18 Fig.

. Adjust the needle-valve RUNNING-IN ("Breaking-in") Abrupt adjustment of the needle-valve may cause the engine to stop, especially when it is new and insufficiently run-in. Obtain a 18x6 propeller for running-in. 1. Running-in on the ground As the speed of the engine does not instantly change with needle-valve readjustment, small movements, with pauses between, are necessary to arrive at the optimum setting.

Start the engine. open the throttle fully . Adjust the neede-valve. Disconnect the glowplugs from the battery. Approx 40˚ open from maximum r.p.m. setting. Make sure that all 2 cylinders are firing. Close the throttle gradually. Find the idling position. Fix the idling position. Re-set the idling position at a little higher r.p.m. Open the throttle fully. Engine stops. Does the engine regain full power? The position where the lowest possible r.p.m. ,with steady running, is obtained.

Adjusting the mixture control valve of the + mark about 1/12 turn (30 ). Normal safe idling speeds are in the region of 2,000 r.p.m.. 1. If the engine hesitates, puffing out Mixture Control Screw a good deal of smoke, before picking up to full speed, it is Turn 30 probable that the idling mixture is too rich. In this case, it will be necessary Screwdriver to turn the Mixture Control Screw Fig.25 in the reverse direction from the + mark (i.e. clockwise) to weaken the mixture.

VALVE CLEARANCE ADJUSTMENT ALL O.S. four-stroke engines have their valve (tappet) clearances correctly set before they leave the factory. However, if, after many hours of running time have been logged, a loss of power is detected, or if the engine has to be disassembled or repaired as a result of an accident, valve clearances should be checked and readjusted, as necessary, with the aid of the O.S. Valve Adjusting Tool Kit. 2.

4. Re-tighten locknut while holding adjusting screw stationary. (Fig.33.) Hold at the screw head. Tighten Locknut. Fig.33 5. Remove 0.04mm feeler, rotate prop through two revolutions and recheck gap. 6. If clearance is correct, loosen the locknut on the other rocker-arm and repeat steps 1 to 5 above. Finally, replace rocker box cover. Remember: Excessive valve clearance will cause loss of power, due to valve (s) not opening sufficiently.
