A. General Warnings:
D. Breaking-in of engine
1.Verify all screws and nuts are firmly secured on the engine. Verify the engine with all wirings
1. Recommended to be used for breaking-in of engine:
well-connected and a complete oil tubing.
l
No.90-No.93 gasoline as the fuel
l
FC two-stroke gas engine oil as the lubricant
2.Consider the engine to be securely installed to the car.
According to volumetric ratio, measure a proper proportion of mixture.
3.Provide a good air ventilation for engine against getting choked. Allow reliable clearance for
Initially, the proportion of 1/20 th-1/25 th of the mixture is recommended for engine to run for
engine to cool down shortly.
4.Double check oil tubes, all wirings after being installing. Failure to do so can cause malfunction
of engine, even damage to engine.
B. Safety Information:
1.Keep away any source of heat/an open fire when re-fueling to the gas tank.
2.Verify no leaky details are found on the gas tank, the fuel tubing/tube joints.
3.Perform a proper manner to start the engine.
the first eight hours. Then, measure it down to 1/30 th or so.
2. For the first four hours, never allow engine speed to run more than 5000 rpm. Then, the
engine comes to normal working. (Note: the proportion of 1/20 th - 1/25 th of the mixture is for
the first 4 hours and the proportion of 1/30 th is for the second four hours.)
3. Never attempt to arbitrarily adjust the carburetor needle during breaking-in. The engine will
run smoothly after breaking-in is performed.
4. Proper proportion of the mixture to be used is essential to perform a smooth breaking-in
procedure and keep engine running in a good manner for long time as well.
4.Always avert touching the muffler, the glow plug which can generate too much heat. Otherwise,
it would cause burn.
5.Recommend to wear the uniform to handle with engine. Take care not to get your clothing ( laps,

Conforming to instruction adjust these needles.
Properly run the engine before adjusting high/low end mixture needles.
Adjust high/low end mixture needles in phase keeping proper inflow of mixture.
Re-adjustment is required for optimum performance.
An improper inflow of mixture will compromise engine performance and/or cause an uneven
running speed.

Therefore, re-adjust high/low end mixture needle until the engine run smoothly.
Not only optimum performance desires for engine speed at a considerate rpm, but it also requires
smooth acceleration and/or deceleration for the engine without stalling.
Note: Incorrect adjustment for carburetor will cause a trail of problems:
-Maintenance
1.Keep the engine surface clean. Always clean oil stains off after use.
2.Blow off the residual fuel and clean the oil pipe and the carburetor.
1.Failure to start the engine.
3.Pour the residual fuel out from the tank for use next time.
2.Instable acceleration and/or deceleration
4.Remove the glow plug if the engine is not in use for a long period of time. Infuse the cylinder
3. Engine is easy to stall.
with 10-20 drops of FC lubricant oil.
5.Store the engine in a dry area with well-packed.
F. Clearance adjustment (between the igniter silicon steel and the
fly wheel magnet)
The normal clearance between the igniter silicon steel and the flywheel magnet is around
0.20mm-0.30mm. Oversize or undersize will affect performance of igniter and cause malfunction.
Please make due adjustments conforming to the following instructions if it goes beyond the normal
size.
-Unlock the two screws on the igniter, turn off the flywheel magnet to the other side.
-Insert one car or two cards( like personal card…) into the clearance, securely fix the igniter and
the flywheel, and then lock the screws.
-Remove the card.
- When you fail to start the engine
1.Check if the tank is filled with fuel.
2.Pull the engine handle putting the glow plug head attached to the
cylinder body or the muffler and see if it functions.
3.Remove the glow plug, put down the engine to check if the cylinder body is flooded and/or
choked.
4.Check if the oil pipe is leaky and the carburetor is clogged.
5.Check if the fuel is smoothly flowing into the carburetor.
G. General information
6.Check if all wirings / connectors are properly connected.
-General usage/information
1.Always provide a proper proportion of fuel and lubricant for engine. Check if the clean fuel is
used.
2.Permit the glow plug to work properly. Check if there are cracks or any phenomena of carbonization is found on the glow plug.
3.Verify all screws and nuts are firmly secured.
4.Check the electric igniter is properly installed and all wirings are firmly connected.
5.Verify there is no leakage on the joints. Check if the muffler is securely installed.
6.Check if the clutch is seriously fixed to the engine.
7.Check if the engine is firm.
8.Check there is no leakage on the oil pipe.
