Tuning:

1. Using the tachometer tune the engine for maximum power

with the high needle (H).

2. Using the tachometer again: richen the high needle (H) until

the engine runs 100-200 RPM less than the maximum RPM.

Now you should richen slightly on the high needle (H).

Keep the engine run at idle for 60 seconds. Insure that the

idle RPM to be constant. If the low needle (L) is too rich, it

may happen that idle RPM drops until the engine stops; Lean

the low needle (L) until a constant idle RPM is achieved.

Check the transition with a quick throttle advance. It should

sound like it is making quick steady power.

Care:

Your carburetor screen will need to be cleaned with clean

gasoline and blow off with compressed air after every flight.

Check the choke and throttle plates for tightness.

Trouble Shooting

Problem1. The engine is flooded.

Solution:

Remove the spark plug; turn the engine to a position where the

fuel runs out and clean it.

Check the connections of spark plug, screws, restart the

engine.if it failed to start again, please send it back to After-sale

service center for repair.

Problem2. The engine starts after being choked but then stops

soon after.

Solution:

The low needle on the carburetor is probably too lean.

Adjust the Low End needle until you achieve a smooth idle and

a reliable transition to high throttle. Generally if the motor

stutters or coughs in the mid range or when the throttle is

advanced, the low end needle is too rich and possibly even the

high end needle.

Problem3. The engine runs rough and is vibrating strongly.

Solution:

Balance the propeller. Check the ignition timing. Check your

plumbing for air/fuel leaks

Check your spark plug for carbon and check the spark plug gap.
