ADJUSTING CARBURETOR
14 a
b
d
e
c
a. To set the high speed needle (large needle sticking out from the carburetor body), turn the screw as
pictured. Initial high speed needle setting should be 2.5 turns (close the needle completely, then back
out 2.5 turns). Clockwise turn will provide leaner setting (lower fuel to air mixture), and counterclockwise
turn will provide richer setting (higher fuel to air mixture).
b. To set the carburetor idle (small needle sticking out from the carburetor body), turn the screw as
pictured. Initial idle setting should leave 1mm carburetor gap. Clockwise turn will provide higher idle
(larger carburetor opening), and counterclockwise turn will provide lower idle (smaller carburetor
opening). For more details about the engine setting, please refer to ENGINE BREAK-IN/SETTING
procedures to properly set the engine.
c. To set the low speed needle (The low-speed mixture screw is located in the end of the carburetor).
turn the screw as pictured. Initial low speed needle setting should be 6 1/2 turns (close the needle
completely, then back out 6.5 turns). This screw controls how much fuel enters the engine at idle and
low throttle. This adjustment will smooth the idle and improve the acceleration to mid speed. Make
this adjustment with the throttle closed, after setting the idle. Turn the screw clockwise gently until it
stops. DO NOT over tighten.
d. Remove the outer foam from filter and make it moist evenly with a few drops of fuel. Put the filter in a
plastic bag and knead it until the foam is saturated, but not soaked.
e. Finally, make sure the air cleaner boot is securely fastened with a zip-tie.
Never run your vehicle without the air filter .If the vehicle will be operated in an area with fine dust, use
filter oil or caster oil instead of fuel. It is important that the foam is only moist to trap dirt and allow air
passage. With the foam too wet, limited air can pass through; therefore, limiting engine performance.

FUELLING
15 a
c
b
a. Remove the cap from fuel bottle nozzle.
b. Squeeze the fuel bottle, insert into fuel, and draw fuel into the fuel bottle.
c. Lift up the lid on the fuel tan and fill car's fuel tank with glow fuel slowly
Be careful. If the tank overflows it might get on your radio gear or on your brakes and you may create
an unsafe driving situation. Always keep your fuel bottle closed when not in use.
Fuel Selection
Choose a fuel from a reputable, brand name company that is approved for car/truck use. Do not use
airplane or boat fuels in your truck. Choose methanol based model engine glow fuel that has a nitro
content in the range 10%-30% and 5% to 18% caster/synthetic oil content for lubrication. Lower nitro
percentages will generally result in a cooler engine running temperature and therefore last longer before
needing a rebuild; cooler-running engines also generally produce less power.
20% nitro is the most widely used fuel in these engines. Fuel color is for identification purpose only and
is not important to performance or durability of your engine.
PREPARING THE ENGINE
16 a
b
c
a. To start an engine, first remove the glow plug.
b. Prime the carburetor by squeezing the primer bulb while watching the fuel come through the line
and just reach the carburetor inlet. Then, give the bulb another 1/4 squeeze(1/8thinch).
BE CAREFUL NOT TO SQUEEZE TOO MUCH or the engine will become flooded. Attempting to start
a grossly flooded (or hydro-locked) engine (full of fuel) can cause serious damage to internal engine parts.
c. Check the glow plug by plugging it into the glow plug igniter. The glow plug element should light up
brightly. If it lights up dimly, then the glow plug igniter is low (and it needs recharging). If it does not
light up or the plug element looks distorted, then the glow plug is bad (replace with new one). After
checking, reinstall the glow plug.
The glow plug used for this engine can be: Thunder Tiger 9281, McCoy #9 / #59, Novarossi C4S /
C5S / C6S,OS #8 / #A3 / #A5, and Picco P6S / P7S.

STARTING THE ENGINE
17 a
Start the engine using either the pull start or hex start (corddless drill required)
d
c
b
When using the dual-start
system to start your MTA-4,
use both hands to hold
the power drill.
d
Check direction of
drill before inserting
into the dual-start
system. It should be
turning clockwise.
a. Turn on the radio (transmitter first, then receiver).
b. Clip the glow plug igniter onto engine's glow plug.
c. Pull Start - Hold the truck by the handle with one hand and pull the pull-start-cord with the other.
Use quick and short pulls and make sure that you are only pulling the cord about 10-12 inches. Pulling
the cord more than 14 inches or all the way will damage the pull-start mechanism. If the cord is difficult
to pull or is stuck it is an almost sure sign that the engine is flooded.
d. Hex Start -Make sure that your drill is set to the clockwise or forward position. Insert the Hex Starting
Shaft to the drill and tighten the drill chuck with the ball end facing away from the drill. BEFORE
inserting the Hex Starting Shaft into the dual start output, squeeze the trigger and verify that the drill
is turning the same direction as is shown on the sticker on the pull start cover.
If the engine becomes flooded: Turn off your truck, and then the radio. Remove the glow plug using a
glow plug wrench and then remove the air filter. Turn the truck over to allow any excess fuel in the engine
to run out. Turn the truck right side up. Reinstall the air cleaner. Slowly pull the pull-start cord about 8
inches, 5 to 7 times. Reinstall the glow plug with the glow plug wrench. Return to step 16b.
CAUTION: Attempting to start the motor by using a counter-clockwise direction could damage
the pull-start mechanism or possibly the engine internal components. Insert the ball end of the Hex
Start Shaft into the Dual Start output. Grasp the drill tightly and squeeze the trigger.
STOPPING THE ENGINE
18 a
c
b
a. Bring your truck to a complete stop and idle. Then, Remove the body clips and body.
b. Using needle-nose pliers or a clothespin, pinch off the fuel line just before the carburetor until the
engine stops (1-2 seconds). DO NOT ATTEMPT TO STOP THE MOTOR BY TOUCHING OR
GRABBING THE FLYWHEEL! These motors have a lot of torque and serious injury could occur
from stopping the engine in this manner.
The exhaust gasses can be very hot, stopping the motor by plugging the exhaust with your finger
could result in a serious burn.
c. Turn off your truck and then the radio

ENGINE BREAK-IN
For a new engine (break-in setting), the high speed needle needs to be set as rich as possible. Turn
the high speed needle 1/4 turn counterclockwise from initial setting (2.5 turns from fully closed). Repeat
step 19b. Keep doing this until the engine stalls at full throttle, then turn the high speed needle 1/4 turn
clockwise. Run the car in an open parking lot with this rich engine setting for at least 5 tanks of fuel to
complete the break-in process. It is normal for a new engine to stall many times during this time due to
the rich setting. When it does, just restart the engine. After break-in, follow the ENGINE SETTING
procedure to set the carburetor for normal operations.
ENGINE SETTING
Due to different fuel formula, operating elevation, humidity . . . etc., the engine may/may not operate
properly at initial setting. Please follow the following procedure to achieve proper carburetor setting. Do
not perform this procedure until the engine has been properly broken in.
a. Start the engine.
b. With a running engine, run the car back and foreth in a straight line (full throttle achieved furing
each passage) in an open parking lot. Repeat and note the sound of the exhaust. Do not hold the
throttle open with car off the ground or the engine connecting rod may break.
c. If the exhaust does not reach a high pitch note, turn the high speed needle (long needle, extending
from carburetor body, pointing up) 1/4 turn clockwise, and repeat step 19b.
d. Repeat step 19c until the engine reaches optimum setting (turning in the high speed needle will no
longer have an effect at full throttle and turning out the needle will cause the engine's full throttle
rpm to drop a little). For normal operations, turn the high speed needle 1/4 turn counterclockwise
from the optimum setting.
e. To set the idle, turn the idle screw in (higher rpm) or out (lower rpm). Basically, the idle needs to be
set at the lowest possible point before the engine stalls.
f. To set the low speed needle (inside the throttle lever), the engine needs to be broken in and high
speed needle needs to be set first.
g. Repeating step 19b every 10 seconds (1 second full throttle and 10 seconds idle). If the engine
rpm at idle drops after a few seconds and stalls, then turn in the low speed needle (clockwise) 1/4
turn. If the engine rpm stays the same or goes up at idle, then turn out the low speed needle
(counterclockwise) 1/4 turn.
h. Keep repeating step 19g until the engine rpm drops (goes to idle rpm, then drops a few more rpm
after a few seconds) but does not stall.

STORING YOUR CAR
To keep your truck in good working condition, there are a few steps that need to be followed:
a. Remove the fuel from the tank. Both your truck and squeeze bottle should always be stored free of fuel.
•Empty any fuel remaining in your squeeze bottle back into the fuel container.
•Draw the fuel in the fuel tank into the squeeze bottle and squeeze it back into the fuel container.
•Repeat the above step as necessary until the tank is as empty as is possible.
•Make sure to store your fuel container out of the reach of children in a cool, dark location and make
sure that the lid is securely tightened.
b. Put the glow plug igniter on the glow plug, hold the carburetor all the way open and pull the pullstart a few times. This will make sure that there is no unused fuel in the engine or fuel lines.
c. Use after run oil.
•Start out by taking an old toothbrush and cleaning off the dirt around the base of the filter. This
will help to keep grit out of your engine.
•Remove the filter from the carburetor.
•Place 2-6 drops (as recommended by after run oil manufacturer) directly into the carburetor.
•Slowly pull the pull-start cord about 8 inches, 3-5 times.
•Reinstall the air cleaner.
d. Clean your truck -storing it dirty can lead to a gummy build up and poor performance.
•Use nitro car cleaner, WD-40 or equivalent to clean up the dirt and oil.
•Use an old toothbrush or a small paintbrush to get to the hard to reach areas.
•A damp cloth works well for cleaning the body. Stubborn dirt and oil on the body is best removed
with any diluted organic solvents (Simple Green, etc).
e. Lubricate the wheel bearings, drive axle joints, clutch bell bearings and suspension pivots using
thin oil.
f. Verify that BOTH the radio and receiver switches are turned off. It is very disappointing to have
dead batteries next time you want to run your truck.

It should shift into 2nd gear within 12-15 feet on a fullthrottle, standing-start acceleration.
b. If you wish to adjust the shift point, first shut down the
engine then open the two-speed access cover on the
transmission case. Align the BLACK adjustment set screw
with the opening on the 2nd gear as shown on the diagram.
c. Using a 2mm Allen wrench, turn the black adjustment set
screw clockwise to make the two-speed shift later; turn
it counter-clockwise to make the two-speed shift earlier.
Only use 1/4 turn increments whenever you adjust your
two-speed.
d. Close the two-speed access cover on the transmission case.
e. Be careful not to touch any hot engine components in the area.
Front & Rear Toe-In / Toe-Out
a. Use a 1.5mm Allen wrench as shown to adjust the front & rear
toe-in.
b. Lengthening the Turnbuckles will increase the amount of toe-in,
Notch
shortening them will increase the amount of toe-out.
c. The notch on the turnbuckle indicates the side that has the righthand thread.
Use it as a guide to determine which way to turn the turnbuckle when
adjusting its length.

b. Turning the upper pivot ball clockwise increases camber towards
the negative side; turning it counter-clockwise increases camber
towards the positive side.
Ride Height
a. The truck ride height can be increased by adding preload clips to
the shocks. Removing preload clips will decrease the ride height.
b. Compress the spring and insert the preload clips between the
spring collar and the shock body flange.
Slipper Clutch
a. Use a 7mm nut driver to adjust the slipper clutch.
b. Tighten the slipper nut until the spring is fully compressed.
c. Once you loosen the slipper nut ?turn.
d. Do not run you truck with the slipper nut any looser than 1/4turn
from full spring compression. Setting the slipper too loose may
result in a damaged spur gear.
13
Shock Springs
Stiffer springs will give you better handling and higher cornering speed on smooth surfaces such as
asphalt, concrete, and hard pack dirt. Soft springs are better for rougher terrain, rock crawling and jumping.
Softer springs will increase the rollover tendency of the truck at higher speeds.

Optional Gearing
Additional gearing is available for your MTA-4 Monster Truck. Additional gearing allows you to match
your engine and transmission to your driving situation. Bigger gears on the clutch bell (or smaller slipper
gears) will result in greater top speed, but will have slower acceleration from a stop (see chart below).
If you change the gearing you will need to reset the gear mesh:
1. Loosen (or tighten if engine was removed) the four engine mounting bolts located on the underside
of the truck until you can just slide the engine forward and backward.
2. Slide the engine up to the spur gear until the teeth on the clutch bell are meshed tightly with the teeth
on the slipper gear.
3. Move the engine back a little bit (1/32" or 0.8mm). Check the mesh by holding the smaller gear with
one hand and rocking the bigger gear back and forth with the other. The big gear should rock back
and forth slightly with little effort. A gear mesh that is too tight will be noisy, have lower performance
and could ruin the gears.
