OPERATING
INSTRUCTIONS
|
The
carburetor enables easy adjustment of the idle speed, idle
mixture and the high speed mixture.
1.
HIGH SPEED NEEDLE VALVE
Locate
an area to install the Remote Needle Valve Assembly using
the bracket provided. This may typically be attached on the
firewall, cowl, or rear engine mount lug area. This assembly
must be in the fuel line between the tank and the carburetor.
The line should not exceed five (5) inches in total length.
2.
HIGH SPEED NEEDLE VALVE ADJUSTMENT
This
needle valve, located on the Remote Needle Valve Assembly,
controls all the fuel that comes to the engine, whether the
engine is running at high, mid-range, or idle speeds. It does
not affect the low speed rich/lean setting. The High
Speed Needle Valves main function, however, is to meter
the high-speed fuel mixture.
As
a starting point for the High Speed Needle Adjustment, completely
close the needle valve (clockwise), then open it (counter-clockwise)
three and a half turns. This setting is an average and may
require further adjustments. For higher altitudes (3,000 -
4,000 feet), close the needle valve approximately 1/2 turn.
3.
LOW SPEED and MID-RANGE ADJUSTMENT
The
rich/lean adjustment is controlled by the slotted
screw located on the side of the carburetor where the low
speed disk is housed. The rich/lean mixture control is set
at the factory and may require only a fine adjustment for
your application. WARNING: DO
NOT RUN THE ENGINE AT A LEAN SETTING. This
screw only turns 1/4 turn to either the right or left of center.
It does not turn all the way around. Turn the screw clockwise
to lean the engine and counter-clockwise to richen
the mixture.
NOTE:
Make sure you are holding your airplane firmly to prevent
it from lurching forward wen the engine starts. After it starts,
maintain your hold until you have reduced the throttle to
a low idle speed.

ENGINE
INSTALLATION
|
The engine
may be installed upright, on either side, or inverted. In any
position, however, be certain that the engine is securely bolted
into place. Use the TEMPLATE supplied for EXACT MOUNTING BOLT
SPACING. |
|
ENGINE
BREAK-IN
|
We recommend
that you mount your engine to a break-in stand to familiarize
yourself with it and with the carburetor operation. It is strongly
recommended that fuels containing more than 10 to 12% nitromethane
be avoided until the engine has been operated about one hour,
for the initial flights adjust the engine to a slightly burbling
sound and a smoky exhaust. After each tank of fuel, the engine
can be leaned until about one gallon of fuel has
been consumed. For both break-in and general operation K&B
500 should be used. |
|
PROPELLERS
|
For most
airplanes, an eleven (11) inch diameter with eight (8) inch
pitch is recommended. For larger and heavier models, a twelve
(12) inch diameter with six (6) inch pitch can be used. Whatever
propeller Is used, make certain it is properly balanced to prevent
excess vibration. |
|
GLOW
PLUGS
|
Use
a Long Reach Glow Plug (K&B No. 7311)
|
|
STARTING
ENGINE
|
With a
full tank of fuel and an ignition battery of no more than
1½ volts, proceed as follows:
1.
With the booster battery disconnected and with the throttle
wide open, place finger tip over the carburetor venturi and
flip the propeller quickly two or three times, to prime the
engine.
2.
Remove fingertip from the carburetor inlet and continue to
flip the propeller several times.
3.
Close the carburetor to approximately one-quarter (1/4) open
and connect the battery to the glow plug.
4.
Slowly turn the propeller (counter-clockwise) and feel
for a momentary resistance, which indicates ignition of the
mixture in the cylinder.
5.
Quickly flip the propeller to start the engine and, then,
disconnect the battery.
