AquaCraft 46 BB Marine Engine - Manual

Needle Valve: The needle valve controls the ratio of fuel to air as it
enters the carburetor.
Idle Mixture Screw: The idle mixture screw controls the ratio of fuel
to air at idle.
Idle Stop Screw: The idle stop screw adjusts how far the throttle closes.
It should be set to allow the throttle to close completely. This will allow
you to stop the engine using the throttle trim on your transmitter.
Throttle Arm: This is the arm that is connected to the carburetor barrel
and is operated by the throttle servo. As the carburetor barrel opens,
the power of the engine increases. Power is decreased as it closes.
It is important to use only fuels that are specifically designed for use
with model airplane engines. The AquaCraft Pro .46 BB ABC engine
will run best on fuel with a 5% to 15% nitromethane content
containing castor oil or a castor-synthetic blend. The engine can
overheat or will not get hot enough for the cylinder to expand
properly if the fuel type is incorrect. Important: Do not use model
fuels with 100% synthetic oil.
After installing the engine into your R/C vehicle, attach the muffler.
Thread the two muffler screws through the crankcase and into the
muffler. Tighten the muffler screws firmly, being careful not to strip the
threads in the muffler.
