adjusted for both the steering and throttle as noted on the
following pages.
Steering Trim: The model should go straight without turning
the steering wheel. If not, tap the trim lever found just above
and to the right of the steering wheel in the direction needed
for the model to go straight. Each tap of the trim button will be
accompanied by an audible tone indicating a change has been
made. It may take several taps to get the correct trim setting.
Throttle Trim: The model should idle without the tires
rotating when the trigger is at its neutral position. If not, tap the
trim lever found just above and to the left of the steering wheel
to reposition the throttle servo and close the carburetor and
apply more brakes. Note that additional braking force is applied
when you push the trigger forward.

which will allow you to disconnect it if you wish to remove
the engine for cleaning.
• TheRPM/Speedsensorismounteddirectlybelowtherear

stripe on it that the sensor reads. Both of these items have
to be kept clean for proper operation. Use compressed
air or a soft brush to remove dust or dirt that can prevent
operation. NEVER use any kind of solvent on either of
these as it will cause the stripe to fall off and the sensor to
fail. If the stripe should fall off replace it with one from the

Engine Break-In and Adjustments
ThenewLosi3.4engineinyourTEN-Thasbeenmachinedto
tight tolerances and does not need an extended break-in. It is
always a good idea to take it easy for the first few tanks of fuel
to let all the gears and moving parts seat into one another. You
will notice after the first hour of operation that the engine will
pickuppower.ItishighlyadvisedthatyouuseNitrotane20%
Sport fuel as the carburetor is factory set for this fuel and other
fuels may require immediate needle valve adjustments. NEVER
use model airplane fuel as it may cause damage to the engine
and void any warranty. If you change fuels or run in dramatically
dierentenvironments(hot/cold,high/lowelevation,etc)you
will probably have to adjust at least the high-speed needle to
prevent overheating and maintain proper performance.
Tuning a Nitro Engine
Adjusting the carburetor is one of the most critical facets of
running a nitro-powered RC vehicle. The fuel mixture is referred
to as being“rich” when there is too much fuel and“lean” when
there is not enough fuel for the amount of air entering the
engine. The amount of fuel entering the engine is adjusted with
high- and low-speed threaded needle valves. The low-speed
needle is located in the front of the moving slide. The high-
speed needle sticks straight up at the back of the carburetor.
Both feature a slotted head that is used as a reference and
receptacle for a flat blade screwdriver for adjustments. The
mixture is made richer by turning the needle counterclockwise
and leaner by turning clockwise. An overly“rich” mixture will
yield sluggish acceleration and performance with thick smoke
from the exhaust. A“lean”mixture can cause the engine to
hesitate before accelerating or, in some cases, to lose power
momentarily after the initial acceleration. A lean mixture also
makes the engine run hotter than desired and does not provide
enough lubrication for the internal engine components,
causing premature wear and damage. It is always advisable
to run the engine slightly rich and never lean to avoid
overheating and possible damage.

Low-Speed Adjustment
The low-speed adjustment affects the idle and slightly-off-idle
performance. The optimum setting allows the motor to idle
foratleast8−10seconds.Themodelshouldthenaccelerate
with a slight amount of sluggishness and a noticeable amount
of smoke. The simplest way to check this is to make sure the
enginehasbeenwarmedupandlettheengineidlefor8−10
seconds. If the low-speed mixture is so far off that the engine
won’t stay running that long, turn the idle stop screw clockwise,
increasing the idle speed. With the engine at idle, pinch and
hold the fuel line near the carburetor, cutting off the flow of
fuel,andlistencloselytotheenginerpm(speed).Ifthelow-
speed needle is set correctly, the engine speed will increase
only slightly and then die. If the engine increases several
hundred rpm before stopping, the low-speed needle is too rich.
Lean the mixture by turning the needle clockwise one hour and
trying again. If the engine speed does not increase but simply
dies, the needle is too lean and needs to be richened up by
turning the needle counterclockwise one hour before trying
again. After you have optimized the low-speed setting, the
engine will probably be idling faster. You will have to adjust the
idle stop screw counterclockwise to slow the engine idle speed
down. The engine should accelerate at a constant pace without
hesitating.

Engine Tuning
After the engine is broken in, you can tune it for optimum
performance. When tuning, it is critical that you be cautious of
overheating as severe damage and premature wear can occur.
