carburetor and reduce engine

5) Check the fuel level. Starting
with a full tank will help reduce
possible operating interruptions
for refueling.
OPERATION
Pump Placement
For best pump performance,
place the pump near the water
level and use hoses that are not
longer than necessary. This will
enable the pump to produce the
greatest output.
As the head (pumping height)
increases, the pump output
decreases. The length, type and
size of the suction discharge
hoses can also significantly
affect the pump’s output.
The discharge head is always
greater than the suction head
capability so it is important for
the suction head to be the
shorter part of the total head.
Minimizing the suction head
(placing the pump as near as
can be to water level) is also
very important for reducing self-
priming time (the time it takes
the pump to bring water the
distance of the suction head
during initial operation).
Suction Hose Installation
1) Use a hose clamp to securely
fasten the hose connector to the
suction hose
in order to prevent air leakage
and loss of suction. Verify that
the hose connector sealing
washer is in good condition.
2) Install the strainer on the other
end of the suction hose and
secure it with a hose clamp. The
strainer will help to prevent the
pump from becoming clogged or
damaged by debris.
3) Securely tighten the hose
connector on the pump suction
port.
Discharge Hose Installation
It is best to use a short, large
diameter hose. This will reduce
fluid friction and improve pump
output. A long or small diameter
hose will increase fluid friction
and reduce pump output.
Tighten the hose clamp securely
to prevent the discharge hose
from disconnecting under high
pressure.
Priming the Pump
Before starting the engine,
remove the filler cap from the
pump chamber and completely
fill the pump chamber with water.
Replace the filler cap and tighten
it securely.
NOTE: Operating the pump dry
will destroy the pump seal. If the
pump has been operated dry,
stop the engine immediately and
allow the pump to cool before
priming.
Starting the Engine
1) Prime the pump.
2) Move the fuel lever to the ON
position. It must be ON for the
engine to run.
3) To start a cold engine, move
the choke lever to the CLOSED
position. To restart a warm
engine, leave the choke lever in
the OPEN position.
