fires and then dies. If the gas line is dry, this may take 20 or more flips.
Step 2: Open the choke and briskly flip the prop through compression. The engine should
start in just a few flips. If it acts like it wants to start but doesn’t, you may need to advance
the throttle slightly.
WARM Open the choke, advance the throttle to very slightly above the idle position, turn
on the ignition and briskly flip the prop through compression. The engine should start in
just a few flips. If it acts like it wants to start but doesn’t, you may need to advance the
throttle slightly.
NOTE: It is possible to flood the engine by over choking. In this case, the spark plug
must be removed and dried of excess fuel. Make sure to have the ignition off when
removing the spark plug.
Engine Maintenance
Fuel tubing throughout the fuel system should be changed periodically and should never
allow any air to enter the system. If your gas line starts to get hard, soft or changes colour,
there’s a good chance it needs to be replaced. Keep in mind that the tubing inside your
tank deteriorates more quickly that anywhere else in the system.
The exterior of the engine should be kept clean and inspected regularly. Tucked away
inside the cowl, it would be easy to miss loose nuts and bolts without frequent inspections.
Dirt inside the cowl area can easily find its way into the carburetor. It should be kept clean
and free of dirt build up.
The carburetor fuel screen should be cleaned periodically also. Carefully remove the
pump cover (inlet side of the carburetor), gasket and pump membrane. The screen will be
visible and can be cleaned after careful removal. If ever the carburetor seems to need
frequent mixture adjustment or acts like it’s starving for fuel, a dirty screen is a likely
candidate for a cause. The carburetor should be inspected, cleaned or reconditioned with
every flying season or after being stored for a long period of time.
The spark plug should be inspected, cleaned and gapped periodically and replaced if it is
fouled or worn. A new plug with every new season is a worthwhile maintenance step.
a) Before using the engine, please check the aircraft propeller and the
engine frame etc. carefully in order to make sure the screws and nuts
fixed. When you installed the engine, you had better use the screw
glue ( such as LOCTITTE 242) to fix the screws or nuts.
b) Please use the clean petrol 93＃. The ratio of petrol and engine oil is
30:1；Carburetor will be seriously obstructed if the engine oil be mixed
up with from different manufacturers or brand.
c) If the engine is running in an idle speed too long, spark plug might be
serious carbonized.
d) Always check and secure the tube between the fuel tank and the
carburetor, make sure there is no air leaking.
e) Keep the surface of the engine clean. Be sure the engine is well heat
dissipation.
f) NOTICE: Please clean the fuel filter in the carburetor periodically,
otherwise failure occurs with needle adjustment and the engine may
