Step 5.
Attach the glow driver.
Step 6.
Turn the engine over using an electric starter.
The engine should fire within seconds of applying
the starter.
Step 7.
Allow the engine to idle for 30 seconds. Adjust the
throttle trim if necessary to achieve a constant
slow idle.
Step 8.
With the glow driver still attached and a helper
securely holding the airplane, advance the
throttle smoothly to full throttle. The engine will
transition to full rpm.
Step 9.
Reduce the throttle to idle and remove the
glow driver.
Setting the Needle Valves
The low-speed needle has a limiter that prevents
over-adjustment. If your engine starts from the above
procedure, but won’t reliably continue to run with the
glow driver removed, follow the steps below.
Step 1. High-Speed Needle Adjustment
With the engine running, advance the
throttle to full throttle while a helper securely
holds your airplane. Carefully pinch and
release the fuel line to temporarily restrict
the fuel flow.
CAUTION:
Do not reach over the propeller while
the engine is running.
The High-Speed Needle settings are:
Correct:
If the high-speed needle adjustment
is correct, the engine will increase rpm slightly
(about 300 rpm) and then die.
Too Rich:
If the engine increases a lot (1,000
rpm or greater), the high-speed needle is too rich
and must be leaned or turned clockwise.
Too Lean:
If the engine doesn’t increase rpm and
simply dies, the high-speed needle is lean and
must be richened or turned counterclockwise.
Step 2. Low-Speed Needle Adjustment
The low-speed or idle needle valve, included
with the SetRight
™
assembly, is preadjusted at
the factory for best performance at close to sea
level conditions. It may be necessary to fine-tune
the low-speed adjustment using the following
procedure:
1.
Start the engine and let it warm up, prior
to attempting any adjustments. Make sure
the high-speed adjustment process is
complete before attempting to adjust
the low-speed needle valve.
Note that the low-speed needle adjustment range is limited,
preventing adjustment beyond the practical range.
