INSTALL THE BASE
Make sure the surface of engine mounting is flush and in the same flat. Improper
installation may lead to deformation of crankcase, bearing, etc. Unstable operation and
performance degradation will happen. The 3.0mm hexagon socket screws are recom-
mended when fixed engine. If installed on other engine platforms, please purchase
adjustment pads to fit between the engine bracket and the engine.
ATTENTION ABOUT STARTING
For the sake of safety, it is strongly recommended not to disassemble the engine and start the
mechanism. If any starting problems, please contact your local dealer or TOYAN technician to solve
them. If return to the factory for testing, TOYAN will provide you with high-quality after-sales service.
If any problem caused by unauthorized disassembly, you will bear the corresponding responsibilities
and expenses

The series of FS-L400BGC requires four special spark plugs for a four-stroke gasoline engine.The
spark plugs require a special CDI for ignition control. when hall detects display the piston running to
the TDC, spark plug will be ignited, fuel will be ignition,then generate will acting.

TOYAN
拓陽精密科技
2.Fuel
Please use gasoline engine fuel with guaranteed quality. Self-matching or fake fuel will greatly reduce
the performance and life of the engine. As it is a four-stroke engine, in order to ensure the normal
operation of the primer, please adjust the ratio of gasoline and fuel in the range of 1:25 to 1:30, and
the oil uses 2T internal combustion engine oil.
Remind!
If the engine is running at very high speeds and on high nitro fuel,The life of the spark plug
does not last long. Please note that engine fuel is toxic. Keep it out of contact with eyes or
mouth and always store it in a clearly marked container and place, and keep out of reach of
children. It is highly flammable. Keep away from open fires, overheating or any source of
ignition
3.
Fuel tank
It is recommended to use a 100cc tank. The tank should be installed on the same flat as the engine.
The gap between the fuel inlet & outlet of the fuel tank and carburetor should be kept within 1 cm
(the carburetor must be higher than the fuel inlet & outlet of the fuel tank). If the gap is too high,
the carburetor's working efficiency will be reduced and the engine will be started adversely. To
ensure clean fuel supply, pls use standard 5mm silicone tubing and properly install oil filters. Since
the engine itself relies on negative pressure to absorb oil, it is recommended the muffling exhaust
pip
e can be used to pressurize the fuel tank

4.Start power supply
The series FS-L400BGC has been installed with a start motor, which can be started with one button.
You only need to purchase standard 7.4v 25C lithium battery to realize quick start. Too low or too
high voltage of starting battery will not guarantee the service life of the starting motor, do not use
incorrect voltage starting battery
g
Please start the engine in an open, airy environment to avoid discomfort from burning gases
6.
Platform for Starting
Since the engine will produce some vibration after starting, please place it on a stable and flat
platform
7.
Heat dissipation
Since the engine has been cooled by a fan, high-speed rotating fan blades will be dangerous,
do not touch. If you find cracks in the blade during use, please replace in time
Remind!
Every time you start the engine, please carefully check whether there are cracks in the blades.
we must replace new if any cracks to avoid the danger of blade spread out during high
-speed
operation

OPERATION AND ADJUSTMENT
Note
Four-stroke engines have stronger torque output than two-stroke engines, so the
corresponding measures should be taken during operation
In order to extend the service life and improve the performance, each engine has been tested at
the factory. You need to do proper running-in and cleaning after receiving the engine. After
continuous running in, the cylinder pressure will be gradually strengthened. Due to the high
simulation degree of th
is engine and the large number of various parts, we do not recommend
you to fully disassemble the engine, we will provide a variety of effective sales to help you
maintain and stable use
1. Check the timing belt and CAM axle box
Please make sure that the marking points on the two pulley can be down at the same time,see P43.
Open the hood and add the grease. Since the mounted CAM is used, please add the solid grease to ensure
stable operation and avoid dry friction of the CAM.
2. Check the power supply
Please confirm that the voltage of 7.4v universal ignition power supply is normal, and full
of electricity
3. Initial Oil Needle Setting
The prerequisite is adequate lubrication and cooling. The engine is run with very important oil
needle settings: The excess oil not only provides rich lubrication, but also conducts heat from
the surrounding metal and further assisted by the fuel nitro methane. the two-stroke model

engines in pre-heating into the cylinder through the crankcase on a longer trip. But The
four-stroke engine, with its intake pipe and carburetor mounted high on the cylinder cap, means
that the rich mixture of cooling fuel and air will flow directly into the cylinder directly.With the
help of fan cooling, it can provide excellent operation experience for every enthusiasts. You can
also buy the TOYAN series of water cooling accessories, so that your engine will be able to
mai
ntain stable operation for a long time.
Remind!
When leaving the factory, each engine has completed the oil needle setting. If you have
misadjusted the oil needle during the use, it is recommended to adjust the main oil needle
to 2.0 laps and the auxiliary oil needle to 1.5 laps. Since the methanol engine needs to
maintain the temperature of the spark plug filament to achieve ignition, when the engine is
in the oil rich state for a long time at low speed, the temperature of the fila
ment will
gradually reduce, resulting in ignition difficulty. Therefore, it is necessary to up the speed
for cleaning oil at intervals to avoid oil enrichment at low speed

Since a four-stroke engine requires a lot of air intake, it is important to set throttle
screws , the minimum throttle opening (idling setting) is about 1.5mm.,For the use of
all kinds of engine enthusiasts. do not use a strong force to twist the throttle valve
screws to adjust the size of the throttle door opening, but using valve screws to loose
throttle, and then pull the throttle rocker arm to adjust. As shown in figure
Loosen the throttle
screw and adjust the
size of the throttle
4. Start
Remind!
It is important to put the throttle in the right position before starting the engine. It is
recommended that the throttle be opened at 30% to start, the engine is not allowed to open
the throttle too far under "no load" conditions, which can quickly overheat and can seriously
damage the engine piston ring and cylinder sleeve.
Connect the spark plug battery and press the start button. Once the engine starts,
disconnect the spark plug battery and keep the engi
ne running slowly under the oil-rich
needle setting. (If necessary, gently adjust the throttle lever to keep the engine idle steady.)
1.5mm
Please keep the throttle
opening larger than 1.5mm

If the engine stops, cooling it for 15 seconds before restarting. Please hold down the start key
within 5 seconds for each start, so as to protect the start motor life. Allow the engine to warm
up for 30 seconds after starting so that the oil in the fuel can be fully lubricated to each working
part. When the engine rapidly drops from high speed to low speed, or when low speed rapidly
rises to high speed, the engine is unstable or the throttle control is slow or flashover, please
confirm the carburetor working status
Rich oil
When the engine has more fuel , smoke is emitted or accelerates slowly, indicating that the
engine has excessive oil, please turn the main oil needle clockwise, 15° as a unit, gradually
reduce the main oil needle, until the sound of engine exhaust is soft and strong, and the
exhaust pipe slightly smokes and the lubricates fuel spray out
Lean oil
If the sound of the engine is too sharp, like the sound of dry friction between metals, th
e
temperature rises rapidly, and the engine is stopped immediately after acceleration, indicating
that the engine has low oil, please turn the main oil needle counterclockwise, 15° as a unit,
gradually reduce the main oil needle, until the sound of engine exhaust is soft and strong, and
the exhaust pipe slightly smokes and the lubricates fuel spray out
Idling Stop
When the engine speed changes rapidly, suddenly adjust from the high speed to the low
speed, the flameout occur
s, please confirm whether the throttle is closed less than 1.5mm, or
gradually reduce the auxiliary oil needle, (clockwise rotation) gradually adjust the auxiliary oil
needle, 20°as units, until the engine maintains a steady idle speed. In the debugging process,
the auxiliary oil needle should not be excessively reduced, so as not to cause engine have lean
oil, we recommend that the minimum value of auxiliary oil needle should not be less than 1
turn.

CARE AND MAINTENANCE
Carefully clean the carburetor and remove dirt and grease from the inlet
If an air filter is used, make sure the filter is clean and free from blockage
Recommended that the air core used for more than one hour should be replaced in time.
Be careful to remove contaminated filter elements to ensure that dirt does not enter the
carbureto
The series of
FS-L400BGC
is a very precise machine that you need to clean timely. Due to the
impact of environment and the fuel when usin
g, the engine parts have a certain amount of wear
and corrosion. So, TOYAN will also provide you with long-term maintenance services. You can
also complete the basic cleaning and maintenance
r
Do not remove timing synchronous belt, you can use alcohol as a cleaning agent to wipe the belt. Do
not use corrosive detergent to clean synchronous belt, to avoid damage
Glow Plug must be treated as consumables. Long running glow plug will not ensure the normal operation
of the engine and you can extend its life maintain the performance of the engine if you use it carefully,
Use appropriate tools for disassembly
Use fuels containing a moderate percentage of nitromethane
Do no

The time to replace the glow plug. expect burned, It also need to be replaced on these situations because
it no longer provides optimal performance,
For example:
a.The surface of the filament becomes rough and white
b.Filament curl deformation
TOYAN
拓陽精密科技
55
c.External material adhered to the filament or plug corrosion
d.The engine will power off when idling
e.The power went out after the engine started
At the end of each operation, empty the fuel tank, energize the glow plug, and try to
restart the engine to burn the possible left fuel in the fuel tank. Repeat this process until
the fuel is cleared from the engine.
Inject some antiseptic oil and briefly start the motor to distribute the oil to the working
parts. Do not inject this oil
into the lubricator nozzles, as this may cause the O ring of the
carburetor to deteriorate Add solid lubricant to camshaft and valve tappet to ensure that
the CAM axle box has enough lubricant for each operation
Note!
These maintenance programs will be stored after a period of time, and there is a risk of
corrosion or startup difficulties, if you need someone to deal with, please contact us
Replacement of running parts
After long-term operation, the friction between the engine components will cause wear and
too large gap, the replacement of related parts will help you maintain your engine better.
When you are in the process of use, there is not flexible start, power reduction, idle speed
instability and so on, please feedback your usage process and poor performance of the
engine to the local dealer or TOYAN, we will serve you wholeheartedly. Parts replacement, we
will provide professional equipment and experienced team. Please do not disassemb
le the
engine without professional tools to avoid the risk of uncontrollable damage to the engine

BUG CHECKING
If the engine fails to start, check the following carefully:
Whether the battery voltage is normal, whether the power is full
Whether the glow plug has failed
Whether the fuel can reach the carburetor smoothly
Do not start the engine when it is flooded. Remove the glow plug, close the oil needle and
press the start button to drain the excess fuel. (Cover the plug hole with a piece of woolen
cloth so that the fuel doesn't spill on you.) If forced to start without removin
g the excess
fuel, it may cause irreversible damage to the starting system, as well as the connecting
rod and crankshaft to strain and deformation
Timing belt adjustment
All TOYAN engines have been tested for timing belt position before they leave the factory.
After several hours of execution, the operating power loss or engine running instability is
found, the timing belt needs to be tested and adjusted to get the correct ignition information
for the engine. Please check a
gainst page 11 of "timing belt timing diagram"
When Turn off at low speed, do not keep it at too low speed a long time. Since the methanol
engine needs to maintain the temperature of the spark plug filament to achieve ignition,
when the engine is in a rich state for a long time at a low speed, the temperature of the
filament will gradually decrease, resulting shutdown. Therefore, it is necessary wait a while to
up the speed oil and clean the oil to keep the temperature of the filament
