6. Install the glow starter onto the glow plug and gently press the
top of the glow starter down and turn in a clockwise direction. This
will lock the glow starter onto the glow plug. To remove the glow
starter, gently press down on the top of the glow starter and turn
counter clockwise.
❏
7. Start the engine by pulling the recoil - Use short, quick pulls.
DO NOT pull the recoil starter's string to the end. You only need 10
to 12 inches of pull to start the engine.
❏
8. Your buggy is equipped with a throttle return spring. It is
installed between the throttle arm and the recoil starter. This will
return the throttle to idle if there is a loss in power for the on-board
radio equipment.
Many times it is helpful to start the engine at around half throttle.
Have a friend pull back on the throttle some while you start the
engine. This may be an indicator that the low speed needle setting
needs to be adjusted. When the engine starts, immediately return
the throttle to idle. If this is not done the engine can over-rev and
cause engine damage. If the engine is difficult to turn over with the
recoil starter, especially if it is brand new, loosen the glow plug a half
turn before starting the engine. This allows some compression to
escape, but the engine will still start. Make sure you tighten the glow
plug after the engine starts. If the recoil starter is still difficult to pull,
the engine is flooded - there is too much fuel inside the engine.
Remove the glow plug, and then turn the engine upside down and
pull the recoil 5 or 6 times. This will clear the engine of fuel, and you
will notice the recoil pulls easier. Replace the glow plug and repeat
the starting procedure.
Tanks 1-2
Your first two tanks of fuel should be running the buggy at a very
rich high-speed needle valve setting. This allows the fuel to carry
as much oil as possible into the engine to lubricate the internal
parts during the break-in.
❏
1. After a minute or two of running back and forth at medium
speeds, slowly accelerating and decelerating the buggy, make sure
the engine is not overheating by putting a drop of water on the
cylinder head. If it boils away within 4 seconds, stop the engine and
allow it to cool. Open the high-speed needle around a 1/4 turn
before starting again. This is a good habit to get into every time you
run to ensure that the engine does not overheat during any run.
Looking at the smoke that comes out the exhaust is also an
indicator of how rich or lean the engine is running. If there is a good
amount of smoke coming out of the exhaust, then chances are
good that you are running rich.
❏
2. Run the buggy back and forth at a medium speed until the tank
is almost out of fuel. Do not allow the tank to run out of fuel. This
leans out the engine and can cause overheating.
❏
3. Stop the engine and allow the engine to cool before the
second tank. This normally takes around 10 minutes.
How To Stop Your Engine
You may have been wondering how to stop the engine. All you
have to do is pinch the fuel line that runs to the carburetor and from
the bottom of the fuel tank. Pinching this line will restrict the fuel
flow and the engine will quit within a few seconds.
Tanks 3-5
Turn in the needle valve (clockwise) around 1/8 turn from the
previous setting for each additional tank. Run the buggy back and
forth. You should notice that the buggy will perform better during
each run. Stop the buggy periodically to check for overheating. If it
is too hot, stop the engine. Wait for it to cool, and then turn the high
speed needle valve counterclockwise 1/8 turn, and restart. After the
5th tank, you should be near to the peak performance of the engine.
10 Ways To Ensure A Long Life From Your Engine:
❏
1. Keep your engine clean. Dirt will act as insulation on an
engine. It will not be able to shed heat as easily. Use a good air
filter to keep dirt out of your engine and clean it often.
❏
2. Do not over-lean your engine.
❏
3. Do not run your engine with little or no load. Don't throttle up
the engine to full throttle when the wheels are not in contact with
the ground.
❏
4. Do not overheat the engine. This goes along with keeping it
clean and not over-leaning the engine.
❏
5. Do not use a fuel with a low oil content. Make sure you use a
fuel from a reputable manufacturer, such as DuraTrax Red Alert.
❏
6. Avoid using old fuels in the engine. Always run all of the fuel
out of the engine. After running for the day, use an after-run oil and
work it into the engine by turning the flywheel or pulling the engine
recoil slowly.
❏
7. Do not use a fuel with a nitromethane (often called nitro)
content over 20%.
❏
8. Do not scratch the piston or cylinder sleeve. Avoid jamming
something into the exhaust port when removing or reinstalling the
clutch or flywheel. Use a special tool called a crankshaft-locking tool,
which is installed in the glow plug hole.
❏
9. Do not use silicone sealer on the engine joints. Silicone sealer
contains acetic acid, which is corrosive if it gets inside your engine.
❏
10. Do not allow any water to get inside the engine. This sounds
easy, but temperature changes can cause condensation inside the
