AGM GAS ENGINE
1. Safety Instructions

4. Maintenance Of The Engine
1)
Before every use, check the engine assembly, propeller and airframe carefully for loose screws and nuts.
Loctite (242,243) is strongly recommended on all the screws.
2)
During the break-in process, engine must running with shock absorber installed. Or the engine will be
seriously damaged by vibration.
3)
Always stand clear of and behind the propeller; never allow anyone including yourself, to be in front of or to
the sides of the propeller when starting or running the engine. Anyone near the engine should wear
protective eyewear. Do not wear loose clothing near the engine or propeller.
2) Functions and Adjustments
3. Engine Adjustment
1)
Every engine has been adjusted to average mixture settings which will most likely allow the engine to
start and run in most locations. However, as altitudes and barometric pressures vary by location, it is very
likely that the carburetor mixture settings will need to be adjusted to obtain optimum performance.
1)
Please use the petrol 93
＃
. The ratio of petrol and engine oil is
30:1; Do not mixed up different brand of engine oil, carburetor
could be seriously blocked.
2)
Breaking-in at 4000RPM/min for 2 hours. Running at low speed
for too long might carbonize the spark plug.
3)
Always check the tube at fuel system, make sure there is no air.
leaking.
4)
NOTICE:
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.
ADJUSTMENT:
A general starting point is 1.5 turns out for the low speed needle (See No.4), and 1.5
turns out for the high speed needle (See No.5).
Adjust the High needle to peak rpm. If ever the engine slows or dies while at full throttle, the high speed
mixture is likely too lean.
Adjust the Low needle until you achieve a smooth idle and a reliable transition to high throttle. If the
engine dies when the throttle is advanced, the mixture is likely too lean. If the engine stumbles when the
throttle is advanced, the mixture is likely too rich.
Caution:
Don't be tempted to run an overly rich mixture. A too rich mixture will only result in
poor engine performance (engine easily off in a quick accelerating and decelerating process),
pre-mature carbon buildup, a fouled plug and excessive exhaust residue. However, a lean mixture
will also damage the cylinder and piston badly. After few times full throttle test and check the
spark plug, it appears to be yellow if mixture had been set properly.
3) Start-up the engine
Step 1:
Close the Choke and turn on the ignition, advance throttle to full position.
Step 2:
Briskly flip the prop through compression until the engine fires and then dies. It may take a few
more flips if this is first time to start the engine after being stored for a long period.
Step 3:
Open the choke and briskly flip the prop through compression, advance the throttle to very
slightly above the idle position, the engine should start in just a few flips.
Step 4:
Open the choke, advance the throttle to very slightly above the idle position, turn on the ignition
and briskly flip the prop through compression.
