Fuel
The Evolution Engine comes adjusted from the factory.
We recommend using high quality Cool Power Omega,
Hangar 9® AeroBlend™ or Power Master fuels containing
10 to 15% Nitro. The Evolution Engine has been test
run using these fuels. If another brand of fuel is used, it
may be necessary to slightly adjust the needle valves to
compensate for the differences in fuel.
GlOW PluG
The Evolution Engine comes with a specially designed
“Super Plug” that prevents idle and transition flameouts.
The plug’s unique shape directs incoming fuel/air mixture
away from the plug element. When replacing the plug,
be sure to replace it with another Evolution Super Plug
(EVOGP1).
STARTING THe eNGINe
Step 1
Fill the tank with the above-mentioned 10 or 15% fuel.
Step 2
Reattach the fuel lines, making sure the vent and clunk
line are attached to the fuel nipple and the muffler
pressure nipple.
Caution
: Do not attach the glow driver yet.
Step 3
With the throttle fully open, place your thumb over the
carburetor and rotate the prop clock-wise through 6
complete revolutions, thus priming the engine.
Step 4
Close the throttle to the idle position and have a helper
hold your airplane.
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.

In some conditions: Due to high altitudes, extreme
temperatures, etc., it may be necessary to slightly adjust
the idle and high-speed needle valves. The high- and low-
speed needles have limiters that prevent over-adjustment.
