LOW SPEED NEEDLE ADJUSTMENT
The low-speed setting affects the performance of idle and slightly higher. The optimum setting is when the
engine runs for at least 8-10 seconds in idle, then, the vehicle then should accelerate with a slight amount of
sluggishness and a noticeable amount of smoke. The simplest way to check this, after the engine is warmed
up, let the engine run in idle for about 8-10 seconds. If the idle mixture is adjusted so that the engine is not
running so long, turn the idle screw clockwise to increase the idle speed. While the engine rotates in idle, pinch
now the fuel line close to the carburetor to interrupt the fuel supply, and listen to the

engine speed. If the low-speed needle is set properly, the engine speed will incre-

ase only slightly, and then die. If the speed before dieing increases several hundred

revolutions and remains there, the low-speed is too rich. If the engine speed not
accelerates, but rather simply dies immediately, the setting is too lean and must be
set by the screw an hour in direction "rich". If the low-speed needle is optimally set,
the engine is idling probably in a little bit higher RPM. Then you have to adjust the
idle set-screw counterclockwise to reduce the idle speed of the engine. The engine
must rev up with constant acceleration and run without breaks or delays.
HIGH-SPEED NEEDLE ADJUSTMENT
After initial spin of the motor must rotate evenly and the typical two-stroke howling with clearly identifi able
smoke plume. If the engine tortures and heavy smoke plume dropouts shows that the mixture of rich and
lean must be set by the high-speed needle setscrew in 1-hour increments „clockwise" until the engine runs
quietly. If there is no smoke to see the mix is too lean and you need to adjust the mixture by turning the screw
counter-clockwise. Don´t be confused by the sound of the engine and the actual
performance. A lean mixture generates a higher exhaust noise, but that does not
necessarily mean higher performance, because the engine is close to overheat.
Ideally, you should run the engine so that it is based on the rich side. The result is
the best mix of speed and life expectancy of the engine.
Caution: The mixture is too lean and the engine is running hot when accelerating
quickly and with a sharp noise, then runs hard, showing no longer smoke or the
speed reduces. This can be caused by the terrain characteristics, atmospheric con-
ditions or drastic height differences. To prevent permanent damage to the engine,
you must then immediately enrich the mixture by turning the high-speed needle
screw at least two hours steps in „counter-clockwise" direction, and be prepared for
further adjustments made before you continue driving.
GLOW PLUG
The glow plug looks like the ignition system in your car. The coil in the middle of the cand-
le is glow red when supplied with a 1.2 - 1.5 V battery, as they contain a glow ignitor is
operated. This is what ignites the fuel/air mixture when compressed in the cylinder. After
the engine fi res, the heat generated by the burning fuel keeps the element hot. Common
reasons for the engine not starting is the 1.5 volt battery being weak or dead, or fuel fl ooded
the motor and the glow plug, or the element burned out. Use a spare glow plug to check the
igniter. If the igniter makes the element glow, remove the plug from the engine to check it in
the same way. A wet glow plug means there is excess fuel in the engine. To remove, put a rag over the head
and turn the engine over a few seconds with your pull starter. Reinstall the glow plug making sure you have
the brass gasket on it. The engine should now start.

OPERATING TEMPERATURE

The ideal engine temperature changes with the air temperature, it should fall within the range 100 ° C - 120
° C. A simple test method is to use a few drops of water on the cylinder head / cooling fi ns. The water should
have evaporated after 3-5 seconds. If it evaporates faster, the engine is too hot, and you have to enrich the
mixture for at least two hours „counter-clockwise" with the high-speed needle. If you are not sure about the
optimum temperature, you should purchase a digital thermometer No. 1964.
