FUEL SYSTEM OPERATIONS
SIGHT GAUGE
The sight type fuel gauge that is standard with this model has been reported to give erroneous readings. The
sight gauge can indicate full fuel when the actual fuel level can be near empty. The cause of such incorrect
readings may be the result of an improper installation. Please check your vent and sight gauge for kinks and
proper line routing. Most importantly, do not take the readings for granted. Always time your fuel burns.
Visually check your fuel by looking inside the fuel tank from the filler neck before each flight.
SIPHONING
When the fuel system is filled to the point it is touching the bottom of the filler neck down to 1/2" below, it is
possible for fuel to siphon. This is caused by a differential in pressure between tanks, un-coordinated flight, or
turbulence. One tank will push fuel into the other. Once the tank overflows out of the vent, siphoning will start.
This will continue until most of the fuel is out of the
OPPOSITE TANK . The way to break the siphon is to stop
the flow from the withdrawals on the non-siphoning tank. Since the chances of siphon are not constant, a
handy way to shut off the fuel from the opposite tank is to clamp the lines with a needle nose vice grip. If you
use the needle vise grips, slip a short segment of fuel line over each jaw to prevent the grips from cutting into
the fuel line. This sounds like a fairly crude way of shutting off fuel, but it is effective. If you desire a more
permanent method, you may want to install valves to shut off the fuel from each tank. If you choose to go this
way, please follow this operational procedure.
Normal Operations: Both valves on. If siphoning occurs, shut
off the opposite tank.
ENGINE OPERATIONS
Provided with the aircraft is an engine manual authorized by the engine distributor. This is a well written
manual explaining many specifics for continued safe and reliable operation of your engine. We urge you to
read and fully understand this manual. In addition, please find the data below helpful in obtaining the most out
of your aircraft.
STARTING
Position the aircraft into the wind and chock the main wheels to prevent rolling. To maneuver the aircraft into
position lift the tail at the strut connect points. Avoid lifting at the tips of the control surfaces.
CAUTION:
Winds above 15 mph may cause the aircraft to lift off when empty. Have an assistant sit in the plane or help
hold it down at the wing strut connect points. Never hold it down at the wing jury strut connect points. Never
hold a strut in the middle!
It is best to start the plane from inside the cockpit. The S-6ES Coyote II can be entered easily by first sitting on
the seat, then pulling up your knees and rotating into position.
Drain the fuel sump under the left hand seat. Prime (if first starting or if it's been 30 minutes since the last start)
3 pumps or pull the Choke. Close the throttle (pull back to close). Flip the ignition switch up for on. Engage
the starter.
NOTE: For Pull Start Systems, move the control stick to the left, grab the start handle, and pull
briskly. Several pulls may be needed. Be sure the ignition is on (switch up). Let it idle a moment and then
advance the throttle slowly. NOTE: After the engine warms up, 2 minutes, close the throttle . If idle is not at
the correct RPM, refer to the engine manual for details on setting the idle. If you encounter starting difficulties
refer to the engine manual for probable causes and solutions.
CAUTION: In cold weather allow at least a 2
minute warm up before applying take-off power.
