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 engines.The AquaCraft Pro .15 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.
Attach the exhaust manifold and muffler (not included) by threading
the two muffler screws (not included) through the crankcase and
into the manifold. Tighten the screws firmly, being careful not to strip
the threads in the manifold.
Attach fuel tubing to the fuel nipples on your fuel tank and route
them directly to their assigned destinations. Use a minimum of
tubing but be careful not to crimp the lines.
Pressure Line
The carburetor of your model engine requires consistent fuel
pressure when running. Pressure is created in the muffler by the
exhaust. Some of the pressure is used to pressurize the fuel tank.
Attach a piece of fuel tubing from the pressure fitting on the muffler
to the vent tube in the fuel tank. This will help to maintain more
consistent fuel flow during running.
Fuel Line
Connect a medium size silicone fuel line from the fuel inlet on the
carburetor to the pick-up tube that is connected to the fuel tank. This
is the line that feeds fuel into your engine.
