GET TO KNOW THE SOUNDS AND SIGHTS OF YOUR
NITRO MARINE ENGINE:
• Rich needle setting means less than maximum RPM. The
engine will operate with a break in the exhaust note. Also
take note that when rich, your engine is going to use more
fuel than normal and you’re going to end up with a lot of oil
and smoke coming out of the exhaust pipe.
If the engine RPM speeds up as the boat goes around the
corner, your engine is likely rich. It is also a good idea to
look at the glow plug element after the fi rst few runs. If it
looks new and shiny, your engine is running rich. It is also
a good idea to change the glow plug after the fi rst 5 runs or
so. As your engine is breaking in, microscopic particles from
inside the engine are coming loose and washing out with
the extra oil from exhaust. As the particles pass through the
engine some of them attach to the element, reducing the
coil’s ability to light properly.
• Lean needle setting means lots of RPM followed by
lean sags in the exhaust note. Fuel consumption will be
minimized and you will not see much oil or smoke exit the
exhaust pipe. If the engine RPM drops off in the corner,
your engine is likely running too lean. Again, it’s a good
idea to inspect the glow plug element. A lean engine run
will show a plug with a distorted coil, broken coil, or missing
coil. It’s also important to note that a lean needle setting will
minimize the dependability of the engine.
TIP:
Most of the
time if the engine quits during a run, the engine was lean.
If you suspect your engine is running lean, bring the boat to
shore as soon as possible and richen the HSN.
• The perfect needle setting means good RPM and a clean,
clear sound. You’ll see some light oil and smoke from the
exhaust pipe and a tanned, slightly dull but not distorted
glow plug element.
TIP:
At the risk of a slower operating
boat, it is best to err on the rich side of the needle setting.
Your engine will last a lot longer and provide you with
winning performance race after race.
GLOW PLUGS:
The glow plug that comes with the engine (SUPG1201) is
your best bet for a replacement plug. However, if you would
like to experiment with different plugs, there are a few basic
guidelines to follow:
• You want to tune your engine to the hottest plug you can
and not burn the plug element out. This will provide you with
the most speed and coolest operation.
• Hotter plugs advance the timing in the engine and should
be used with lower nitro fuels. Be warned this can cause
pre-detonation.
• Colder plugs retard the timing in the engine and are typically
used with higher nitro fuels.
WAYS TO ENSURE A LONG LIFE FOR YOUR ENGINE:
•
Keep your engine clean. Dirt will act as insulation on an
engine. It will not be able to shed heat as easily.
• Do not over-lean your engine.
•
Do not overheat the engine. This goes along with keeping
it clean and not over-leaning the engine.
•
Make sure that you use a fuel from a reputable
manufacturer that is labeled as model engine fuel.
•
Avoid using old fuels in the engine. At the end of the day, run
all of the fuel out of the engine, use after run oil and work it
into the engine by rotating it a few times using the starter.
•
Store your engine someplace where it will not be subjected
to extreme temperature changes.
