Section 5: Starting the Dynamite .15S Engine
Operation
m
3. Turn on your radio system and attach a fully
charged glow igniter (DYN1925) to the glow
plug. Insert the starting wand into the Tiger
Drive and actuate the starting switch until
the engine begins to run. If the engine does
not start, place your index finger over the
carburetor and actuate the starter until you see
fuel enter the carburetor through the fuel line.
Note
: Stop operation immediately
if the engine enters a hydro-locked
condition as serious engine damage
may occur if operation is continued.
Remove the glow plug, invert the
boat and operate starter to remove
raw fuel before resuming normal
operation.
You may have to “blip” the throttle on the
transmitter (applying throttle on/off) while
trying to start the engine. New engines are
harder to start because of the tight piston/
sleeve fit. Never start an engine at 1⁄2 to full
throttle, as this will cause over-revving which
may cause premature wear and breakage.
During the first tank of fuel, advance the idle
via the idle adjustment screw more than normal
to prevent stalling at idle due to the rich
fuel mixture for break-in. Pinch the fuel line
nearest the carburetor to stop the engine.
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.
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 the separate Dynamite .15 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.
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 to set is the idle screw. To obtain
a higher idle, turn the idle screw clockwise; for
lower idle, turn the idle screw counterclockwise.
Replacement Parts
In the event that you need to replace an
engine part, there is a complete parts listing
in the Dynamite .15S instruction manual.
Exploded views will help you to select the
correct parts and make minor repairs.
Head Shims
Several head shims are added at the factory to
make the engine easier to start when new. After
break-in, you may remove all but one of these
shims to increase compression and power.
Maintenance
Lube the gears inside the drive with waterproof
grease every 30 hours of use. Check all
screws for tightness after each run.
