Break-In

The first run on any engine, whether 
2-cycle or 4-cycle, is critical to the
future of the engine itself. During this

time, metal mating parts (piston and

cylinder, ball bearings, etc.) wear in.
Care must be taken that the engine is
clean and free of any dust or grit that

may have accumulated while building
the model.

There are two accepted methods for

breaking in a new engine: test stand
mounted and run or aircraft mounted
and run. Either method is acceptable;

however, mounting the engine to a test

stand allows the engine to be observed
throughout its operation, as well as
elevating it above the ground and away
from harmful dust and dirt.

Note: Because your engine may have
been siting for an extended period of
time prior to running it, a few drops of
light oil applied through the crankcase
breather nipple (19 on the exploded
view) and down the push-rod tubes
(40) will ensure proper lubrication for
the first run.

Regardless of the mounting method
chosen for break-in, the following
procedures are applicable:

1.  Use of a fuel as described in the

“Support Equipment” section on 
page 3 of this manual for “break-in”
purposes is perfectly acceptable.

2.  Use the proper glow plugs. Your
engine includes the Hangar 9/McCoy

MC-4C (HAN3010) glow plugs,
which are standard replacement glow
plugs for these engines.

3.  To select the correct propeller, refer
to the "Propeller Selection" chart on
page 16 of this manual. Remember to
balance the propeller prior to use.

4.  Ensure that the high-speed needle
valve (85) is opened (turned
counterclockwise) five full turns. This
guarantees a very rich setting

Do not adjust the low-speed needle
valve (89) at this time. The low-speed
needle valve is preadjusted at the
factory for initial break-in. Specific

instructions for adjusting the idle 

of engines (FA-30S(H)) using an 
“air-bleed” type carburetor will be
described in the section “Carburetor

Adjustments for Air Bleed
Carburetors” on page 7.

5.  The use of a tachometer is highly
recommended since the adjustment of
a 4-cycle engine, while similar to that
of a 2-cycle engine, is more difficult to

“set by ear,” making it much easier to

damage the engine by “over-leaning.”
