Very Important  
FAILURE TO READ AND FOLLOW THESE INSTRUCTIONS BEFORE YOU PROCEED MAY RESULT IN ENGINE  
DAMAGE AND THE VOIDING OF YOUR WARRANTY!  
Introduction  
Congratulations on purchasing a Zenoah® engine. Cared  
This instruction manual has been developed to ensure  
for properly, these high-quality, finely crafted engines will optimum performance from the Zenoah engine you have  
offer many years of reliability.  
purchased. It’s important that the instructions are read  
thoroughly prior to mounting and running the engine.  
Safety Instructions  
This manual describes the engine’s features and func-  
tions. For specific information on mounting, see the  
instruction manual included with the model airplane, heli-  
copter or boat in which you intend to install the engine.  
7. Use a thickly padded glove when hand starting  
the engine.  
8. Make all carburetor adjustments from behind  
the propeller.  
This model engine will give you considerable pleasure,  
satisfaction and performance if you strictly follow these  
safety instructions and take heed of the warnings as to  
the engine’s safe and proper use. This engine has more  
than enough power to cause harm if misused or if the  
safety precautions are not observed.  
9. To stop the engine, the black lead wire from the  
coil should be grounded to the engine body, or use the  
throttle linkage to shut off the air by closing the throttle  
valve completely.  
DO NOT USE HANDS, FINGERS OR ANY OTHER PART  
OF THE BODY TO STOP THE PROPELLER. DO NOT  
THROW ANY OBJECT INTO A PROPELLER TO STOP IT!  
Always  
10. Ensure that all spectators, especially children, are at  
least 20 feet away when you start running the engine.  
1. Use genuine parts for replacement.  
11. Make sure your fuel is kept in a safe place well away  
from sparks, heat or anything that could ignite the fuel.  
2. Check the propeller, rotor (helicopter) or screw  
propeller (boat) prior to each time the engine is used.  
If nicked, scratched, cracked or damaged in any way,  
replace it with a new one.  
Recommendations  
1. Use safety glasses or goggles when starting and  
running your engine.  
3. Use the correct size and pitch of propeller for your  
engine; refer to the propeller chart in this manual.  
2. Do not run the engine in the vicinity of loose gravel  
or sand. The propeller may throw such materials into  
your eyes. The engine could also ingest these harmful  
materials.  
4. It is extremely important to balance the propeller  
prior to installation of the engine. Failure to do so may  
cause damage to the Zenoah engine and/or the airframe.  
Securely tighten the propeller nut against the washer  
and propeller.  
3. Avoid loose clothing when operating your model  
engine, as it could become entangled in the propeller,  
creating the possibility of bodily harm. All loose objects  
(screwdrivers, pencils, nickel cadmium glow drivers,  
etc.) should be removed from your pockets so that they  
do not fall into the propeller.  
5. Inspect the tightness of the propeller nut prior to  
each flight.  
6. Keep your face and body away from the path of the  
propeller blades when starting or running your engine.

Caution  
Disassembly  
®
1. Model engines get very hot while running. Do not  
attempt to handle them until they have cooled.  
The Zenoah engine can be disassembled or reassem-  
bled without any specific difficulties. Refer to the Engine  
Maintenance Section for specific instructions on these  
procedures. If you need service to your Zenoah engine,  
please send it to the authorized service center at the  
following address:  
2. Always run your model engines in a well-ventilated  
area. Similar to automotive engines, model engines pro-  
duce harmful carbon monoxide fumes.  
3. Never modify the flywheel.  
Horizon Hobby, Inc.  
4. Check the flywheel. If it’s damaged, replace it with a  
new one.

5. When mixing the fuel or operating the engine, do so  
in a well-ventilated area  
Engine Parts Identification  
6. Remember that model engines produce a substantial  
amount of power, more than enough to seriously injure  
people and/or do considerable damage to property.  
Always use common sense, skill and constant obser-  
vance of safety precautions.  
It’s important to be able to identify the parts of your  
Zenoah engines. Attached you will find an exploded view  
of Zenoah engines, as well as a chart including part  
numbers and descriptions. This will assist you in easily  
and rapidly identifying the respective parts of your  
Zenoah engine.  
Support Equipment  
The following items are not included with your Zenoah  
engine but are necessary for operation.  
Fuel—Mix gasoline and 2-stroke oil at a mixing ratio of  
25-40:1.  
Note: Be sure to use a gasoline-resistant fuel  
tubing (do not use any silicone rubber tube).  
Never use any alcohol fuel or alcohol-added  
fuel as this will damage the rubber part of  
the carburetor.  
Propeller—Refer to the Propeller Selection Chart located  
on Page 8 to determine the best initial propeller for your  
particular application.  
Manual or Electric Starter—For manual starts, a  
chicken stick is highly recommended. Never use your  
fingers to start any model engine as you could be  
injured. If you must hand-start a gasoline engine, be  
sure to protect your hand with a heavily padded glove.  
There are a variety of heavy-duty electric starters on the  
market that can be used.

Mounting the Engine  
Make sure the engine is mounted on the aircraft using  
aircraft grade plywood that’s at least 6mm in thickness  
for the G26 engine, and 10mm in thickness for the G38  
through GT80 twin, or a mount of equivalent strength.  
Make sure it’s firmly mounted with 4 bolts.  
1. Be sure to set flat washers or a metal plate on the  
reverse side of the mount to prevent the bolts from sink-  
ing into the mount. Periodically check the engine mount  
for loose bolts.  
2. Since the engine is equipped with a floatless carbure-  
tor with a diaphragm pump, the direction of the cylinder  
and position of the fuel tank can be freely selected.  
3. If the engine is mounted on a shock (rubber) mount  
placed between the engine and the firewall for anti-vibra-  
tion, check the hardness of the rubber, making sure it’s  
not too soft, in order to avoid excessive vibration during  
engine operating rpms. Note carefully if the engine is  
vibrating at idle, as excessive vibration can result in  
erratic engine operation due to overflow at the carburetor.  
4. It is suggested that the bolts for the muffler be coated  
with threadlock when mounting the muffler to the engine.  
Operation  
Break-In  
Coil  
No specific break-in is required. The engine is gradually  
broken-in as it is used, and the output power increases  
gradually as the engine breaks in.  
Starting the Engine—Aircraft  
Magnet  
Before attempting to start the engine, be sure to read  
through all the steps for starting the engine as outlined  
below:  
Fig 1-A  
Fig 1-B  
1. Make sure the spark (glow) plug(s) are installed and  
tightened. Check the condition of the plug cap for cracks  
or breaks.  
Zenoah engines are equipped with the ultra compact  
C.D.I. type flywheel magneto ignition system and should  
be started according to the following procedure:  
2. Be sure the propeller is properly secured.  
Note: The magneto system is timed in such a  
way that when the compression stroke starts  
(refer to Figure 1-A) sparks are never produced  
on the spark plug, no matter how fast the pro-  
peller is flipped. The correct starting procedure  
is to quickly flip the propeller when the edge of  
the magnet on the rotor is approaching the coil  
(Figure 1-B). This means that the propeller  
should be quickly flipped at about 90 degrees  
in crank angle before the compression stroke is  
about to start.  
3. Make sure the fuel tank line(s) are properly connected.  
The main line should be connected to the carburetor  
spray bar.  
4. Be certain the mufflers are installed properly.  
5. Fill the fuel tank.  
6. Choke the engine and turn the propeller through a  
few times until the fuel appears at the carburetor.  
7. Set the throttle valve at the idle position or at the  
position slightly open from idle.

Operation (continued)  
8. Quickly flip the propeller in a counterclockwise  
direction according to the procedure described in  
the note above.  
body, or the throttle valve should be closed completely.  
Installation of a “stop” or “kill” switch is recommended.  
Red Lead  
9. The engine should start after a few flips of the  
propeller.  
Black Lead  
10. Be sure to open the choke when the initial firing  
of the engine is heard.  
11. When the choke is opened, be sure to close the  
throttle valve to a position near the idle position before  
the next flipping of the propeller is attempted.  
CAUTION: If the engine is started when the throt-  
tle is wide open, a great thrusting force will be  
generated, which can be very dangerous.

12. If you do not use a chicken stick to start the engine,  
be sure to wear a thick glove when flipping the propeller  
and use all fingers, except the thumb, for the flipping  
operation.  
Refer to the example shown in the following diagram.  
Carburetor Adjustment  
The carburetor is provided with three adjustment screws,  
which are factory set to the best (approximate) posi-  
tions. They may need minor adjustment, depending upon  
the temperature, humidity, atmospheric pressure (alti-  
tude), etc., of the area where the engine is being used.  
13. Do not over-rev the engine. These engines are  
designed to develop maximum output with the standard  
muffler and the recommended propeller size. Please  
refer to the propeller chart on page 10 to confirm the  
®
proper propeller for the applicable Zenoah engine.  
Low-Speed Needle  
High-Speed Needle  
Starting the Engine— Helicopter and  
Boat  
1. Fill the tank with fuel.  
2. Push the priming bulb located on the carburetor until  
fuel appears in the priming bulb (for helicopter).  
Idle Screw  
3. Choke the engine and open the throttle valve approxi-  
mately 1/3–1/2 of the full open position.  
1. Start the engine without making any adjustments.  
4. Quickly pull the starter cord until the initial firing of  
the engine is heard.  
2. Make adjustments only when the engine shows signs  
of inefficient operation.  
5. When the initial firing is heard, open the choke, set  
the throttle valve at the idle position or at the position  
slightly open from the idle position and quickly pull the  
starter cord a few more times until the engine starts.  
3. Standard settings of each needle is as follows:  
a. Low-Speed Needle: 11/8 plus/minus 1/4  
b. High-Speed Needle: 13/8 plus/minus 1/4  
6. For helicopter operation, you should adjust the rotor-  
pitch to obtain a 9,000 to 10,000 rpm of the engine at  
full throttle operation.  
Idle Screw: Turning this screw clockwise increases the  
idling rpm. Turning it counterclockwise decreases the  
idling rpm.  
Stopping the Engine  
The ability to shut down the engine in an emergency is  
extremely important. For stopping the engine, the black  
lead wire from the coil should be grounded to the engine  
Low-Speed Needle: This is the fuel adjust screw (not  
the air screw). Turning this needle clockwise makes the  
gas mixture leaner, and turning it counterclockwise  
makes it richer.

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.  
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.  
Note: Do not tighten the high and low speed  
needles too tightly.  
Engine Care and Maintenance  
• Engine oil  
Recommendations  
To extend the life of your Zenoah® engine, the following  
is recommended:  
• Washing gasoline  
• Brush  
1. Use a Zenoah quality 2-stroke oil mixed at 32 to 1.  
2. Use the recommended spark plugs.  
• Scraper  
• Cloth  
3. Use the proper propeller size and balance the pro-  
peller prior to use.  
The engine can be disassembled or reassembled without  
any specific difficulties, but note the following:  
4. Always adjust the engine to a slightly rich setting.  
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.  
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.  
Note: Because the crankshaft is of the assembly type,  
do not disassemble, hit or twist its end.

This chart enables you to select the best propeller for  
initial setup of your Zenoah® engine.  
Note: All recommendations are based on engines using  
APC brand props.  
Remember, it’s imperative to balance each propeller  
prior to installation onto your Zenoah engine. Failure to  
do so may cause unwanted vibration in your aircraft.
