The break-in settings for the carburetor

needles are:

• High-speed needle: 1.5 turns open

• Low-speed needle: 1.5 turns open

Use a tachometer (HAN111, HAN156, or

telemetry) to tune the engine based on RPM.

To lean the high- or low-end fuel mixture, turn

the high- or low-speed needle clockwise. To

enrich the high- or low-end fuel mixture, turn

the high- or low-speed needle counterclock-

wise. It is best to make all the carb adjust-

ments with the engine turned off.

WARNING: Always adjust the

carburetor from behind the

propeller. Keep all loose items

away from the propeller at all times.

Never reach over or around the

propeller.

1. Start the engine.

2. Move the throttle stick up until the engine

is running at approximately 2,000 rpm.

3. Move the throttle stick up to full (open)

throttle. If the engine runs rough, the fuel

mixture is too rich. If the engine stops run-

ning, it is too lean.

4. With the engine shut down, either enrich

or lean (as indicated by the test in Step 3)

the high-speed needle screw by 1/16th of a

turn and restart the engine. Turn the high-

speed needle clockwise 1/16 turn to lean

the high-end fuel mixture.

5. Repeat Steps 3–4 until the engine is

running reliably at full (open) throttle.

Engine Tuning

Until the engine is broken in, use an electric

starter to start the engine. Once it is fully

broken in it can be started by hand, but it is

easier and safer to start the engine with an

electric starter.

1. Turn on the ignition.

2. Close the choke valve.

3. If Using an Electric Starter

a. Rotate the propeller in a backwards

direction against compression.

b. Push the start ﬁrmly against the nose

cone and engage. The engine should ﬁre

relatively quickly, within 1-2 seconds.

c. Turn off the choke and engage the starter

as before until the engine starts.

If Using a Starting Stick or Flipping by Hand

a. Rotate the propeller counter-clockwise

until against compression.

b. Flip the propeller through compression

until it ﬁres.

c. Turn off the choke.

d. Flip the engine through compression as

before until it starts.

4. Let the engine run at mid-throttle for 45

seconds to stabilize the temperatures.

a. If the engine doesn’t start quickly, disen-

gage the starter. Continuously running

the starter can ﬂood the engine.

b. Check to make that fuel is moving

through the carburetor system.

c. If the engine appears not to have any

fuel, repeat the priming procedure

above.

d. Repeat 1–4 of Starting and Running the

Engine.
