Operation (continued)

High-Speed Needle: Turning this needle clockwise makes the gas mixture leaner, and turning it counter- clockwise makes it richer. Set this needle at a position which is 1/4 open from the maximum rpm position while the aircraft is on the ground.

Note: Do not tighten the high and low speed needles too tightly.

When the engine has just started and is not warm enough, there may be insufficient acceleration and the engine may die. Be sure to allow the engine to warm up at idle for a few minutes before conducting normal operation.

Engine Care and Maintenance

Recommendations

To extend the life of your Zenoah® engine, the following is recommended:

1.Use a Zenoah quality 2-stroke oil mixed at 32 to 1.

2.Use the recommended spark plugs.

3.Use the proper propeller size and balance the pro- peller prior to use.

4.Always adjust the engine to a slightly rich setting.

5.For long-term storage, make sure there is no fuel left in the tank or the engine. Remove the spark plug(s) and apply several drops of high-quality oil (e.g., Marvel Air Tool Oil) to the top of the engine and into the spark plug hole. Rotate the crankshaft several times. Store the engine in the box it came in or on the airplane with the nose down in order to keep oil in the bearings.

Servicing the Engine

Required Tools

•Regular screwdriver

•Phillips screwdriver

•Hexagonal wrench (4mm/5/32")

•Open wrench (19mm/3/4")

•Plastic hammer

•Thickness gauge

•Tapered round rod

•Liquid gasket (Permatex or equivalent)

•Thread lock (Blue Threadlock Z-42 or equivalent)

•Lithium grease

•Engine oil

•Washing gasoline

•Brush

•Scraper

•Cloth

The engine can be disassembled or reassembled without any specific difficulties, but note the following:

For disassembling, the special tools shown in the parts list are required (stopper, puller assembly), in addition to general tools. Be sure to use a new gasket when the crankcase and cylinder have been disassembled.

Note: Because the crankshaft is of the assembly type, do not disassemble, hit or twist its end.

Disassembly

1.Dismount the engine from the model.

2.Remove the carburetor and insulator carefully without damaging the gasket.

3.Remove the muffler.

4.Remove the spark plug and ignition module.

5.Remove the propeller hub.

6.Remove the rotor (flywheel). If it cannot be detached, use a plastic hammer and hit the part lightly.

a.Screw the stopper in place of the spark plug, then turn the rotor counterclockwise until the piston touches the stopper. Take care as it can cause dam- age to the piston or connecting rod if the stopper is not screwed in to the bottom.

b.Loosen and remove the rotor securing nut.
