To adjust your needles you will need to know a few terms. If you want to Lean your motor (lean = less fuel
reaching the motor), you will need to adjust the needles clockwise. To Richen (rich = more fuel reaching the
motor) or Fatten your motor you will want to turn the needles counter clockwise. Adjustments to your needles
should be made in very fine increments. I would suggest thinking of your needle as a clock. There are 12 hours
on your clock. For example if you want to lean your top end needle one hour, you would turn the screw in,
or clockwise, one twelfth of a turn. You should make adjustments in one hour increments and NO MORE!
Getting a nice long flat head screwdriver can go along way in making turning your engine easier.
Adjusting your Needles
Section 4 : Breaking in your Engine
The break in process is fairly time consuming, but please make sure to follow all the steps carefully. Out of
the box, the piston sits inside the sleeve very tightly.You need to break this in so that the piston and sleeve fit
together perfectly. The only way to do this is to get the engine up to operating temperature, and allowing it to
cool back down. These nitro motors run on compression, which requires a very precise fit between the piston
and sleeve. The whole point of the break in process is to allow your piston and sleeve to seat together, reaching
running temperature, with lots of lubrication, then allowing it to cool back down to room temperature. The
piston and sleeve fit together best at around 200 degrees to 215 degrees Fahrenheit. It is not necessary but
highly recommended to use a temperature gun during the break in process,but if you have one, by all means
use it. You can use the “spit method” if you don't have a temperature gauge. To do the spit method you take
a drop of spit or water and place it on top of the cooling head. The spit/water should evaporate within 3-5
seconds. It should not pop or sizzle. If it does, than your engine is running too hot. If it takes longer to than
3-5 seconds, your engine is running to cold. You do not have to complete the break in process all in one
session, but you must complete each individual step. Before you start, It is a good idea to take the glow plug
out and pull the starter easily until the piston reaches the bottom of the stroke (place where piston is before it
starts to return to the top of the head) and make a mark on the flywheel so you know where bottom dead center
(BDC) is because when you put the glow plug back into the engine you need a reference point. You will need
something to place the car on during the break-in process that allows the wheels to be off of the ground. You
can use pretty much anything such as a cement block, toolbox or whatever you have around the garage.
Step 1
: Get your fuel and glow igniter ready. We recommend using 20% nitro fuel. This can be
purchased at any of the major hobby shops. Any brand will work , although I would suggest using one
with a higher oil content if you want your engine to last the longest it possibly can. You will need to use
a fuel bottle to fill the tank of your vehicle. Squeeze all of the air out of your fuel bottle and stick it in
your gallon or quart of fuel. Release the fuel bottle and it will create a vacuum effect filling your fuel
bottle. Now fill the tank of your vehicle. Your glow igniter should have been charging for at least 8 – 10
hours.To stop your engine, you should pinch the fuel line leading the carburetor until the engine is off.
Step 2
: You must prime the fuel lines to get fuel into the carburetor. There are a number of different ways
to do this, but the easiest way is as follows: Hold your finger on the exhaust pipe opening and pull the
pull starter until you see fuel traveling through the fuel line. Stop when the fuel gets to the carburetor.
Remove the air filter and put 2 drops of fuel in the carburetor to prime the engine.
Step 3 : Turn on your radio and turn the switch to the vehicle to the on position. Re-Check the controls to
make sure there is no interference.
P
ut your glow plug igniter on the glow plug and pull the starter using a short quick motion.
(Do not force or
pull the pull cord all the way out as this can damage the engine and pull start mechanism).
The engine should start in a few pulls. If engine feels very hard to pull it may be hydro locked. This is
when there is too much fuel in the engine meaning the engine is flooded. To fix this, take the glow plug
out with a cross wrench, turn the car upside down and pull the starter a few times to get the excess fuel out
of the engine. Put the glow plug back in, put the igniter back on the plug and try to start again. Once the
engine fires up, you may need to adjust your idle screw. You do not want the tires to be spinning at this
point, if they are, turn the idle down.

Insert a few drops of fuel
into the carburetor
Insert a fully charged glow plug igniter
into the top of the engine and attach
it to the glow plug.
Make sure the vehicle is lifted off the
ground and is sitting on a toolbox or
other object so that the wheels can freely spin.
WARNING:DO NOT HAVE THE WHEELS TOUCHING THE GROUND.SOMETIMES
THE CAR COULD BE SET INCORRECTLY AND CAUSE THE CAR TO MOVE ON ITS
OWN WHEN FIRST STARTED.
Insert a few drops of fuel
into the carburetor
Make sure the igniter is firmly attached
before starting the vehicle.
