Breaking in Your Engine
The first start-up of the engine is the most critical
moment of the engine’s life, dictating how the engine
will perform from that time forward. Turn on your
radio system and attach a fully charged glow igniter
(DYN1925) to the glow plug. Start the engine with
therecoil (pull-start) on the engine.
During break-in, the low-speed needle should be
slightly rich and the high speed needle should be
very rich. After a few tanks of fuel, begin to lean
the engine out. Adjust the high-speed needle 1⁄16
of a turn at a time. It generally takes about five to
six tanks of fuel before you want to lean out the
engine until it supplies good power. Do not skip
this process of break-in. Failure to follow this
procedure could damage your new engine. For
further details on breaking in your engine, please see
Section 3 of the Dynamite® .15S instruction manual.
Note: It is common for an ABC
engine to go through a glow plug or
two during break-in.
Needle Settings
When adjusting the settings, always adjust the
needles in small increments, about 1⁄16 of a full
turn at a time. Do not set the engine too lean, as it
shortens the reliability of the engine. Please refer to
Section 4 of the Dynamite .15S instruction manual
to learn more about setting the needle valves.
After you have attained the correct needle settings,
the engine will have a strong sounding, high-pitched
whine at full speed, and a thin trail of blue/white
smoke will come from the exhaust.
Idle Adjustment
The last setting is to set the idle screw. To obtain a
higher idle, turn the idle screw clockwise; for lower
idle, turn the idle screw counterclockwise.
Replacement Parts
There is a complete parts listing in the
Dynamite .15S instruction manual in the event that
you need to replace an engine part. Exploded views
will help you to select the correct parts and make
minor repairs.
