Engine Starting and Break In
Your First Runs
If this is your first nitro vehicle, we highly recommend that you have an
experienced nitro tuner help during the first startups and runs. He will be
able help you properly adjust your engine for reliable performance.
Before attempting to start your new buggy, be sure to read this section
and fully understand each step before starting your engine, Pay particular
attention to the needle settings recommended for starting and to the break in
procedures suggested below. Always use the proper fuel and glow plugs.
Fuel and Glow Plug
Note: Using the proper fuel and glow plug is vital in achieving
reliable performance and is a must for long engine life. You
must use fuel and glow plugs that are specifically designed for
model car use.
Never use any type of model airplane glow fuel. We recommend a high-
quality car fuel containing 20% nitro methane (Blue Thunder
™
20% Sport
Fuel is recommended). A glow plug is included that is ideal for breaking
in your new engine. During the break-in process, it’s not uncommon to
go through one or two glow plugs, as microscopic particles of metal
(from the cylinder/piston wearing in) bond themselves to the plug element
causing glow plug failure. We recommend the Dynamite
®
MC-59 Glow Plug
(DYN2508) as the best replacement glow plug for this engine.
Air Filter
A clean properly oiled air filter is a must to keep dirt out of the engine. Use
the included air filter and saturate the foam element with oil.
Starting Your Engine for the First Time
Break In
The first startups and the first 3 to 4 tanks of fuel while your engine is
running is the most critical of its life and, in many ways, dictates how well it
will perform and how long it will last.
During the first runs, when the engine starts, the exhaust should emit blue/
white smoke indicating that the engine is rich (a good thing during break in).
During the first tank of fuel, you may wish to set a higher than normal idle
speed in order to keep your engine from stalling. Drive your buggy around
while blipping the throttle, and avoid operating the engine at full throttle for
more than 2–3 seconds at a time. Run the entire first two tanks of fuel in this
manner. After the first two tanks, begin leaning out the high-speed needle
valve 1/8 turn at a time. It usually take about 5 or 6 tanks of fuel before
you’d want to start leaning your engine for maximum power. Patience will be
rewarded after break in with an engine that performs reliably to its maximum
power potential. Remember glow plug failure is a common occurrence when
breaking in a new engine. To test your plug, let the engine idle at a properly
adjusted low-speed setting with the glow igniter attached. Then, remove
the igniter. If you hear no appreciable change in engine rpm, the plug is still
good. If the engine loads up and the rpm’s decrease, it’s time to replace the
glow plug.
Starting the Engine
1. Fill the tank with fuel.
2. Turn on the transmitter and receiver and confirm that the radio
system is working properly.
3. Attach the glow driver to the glow plug.
