Starting the Evolution Engine
Fuel
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 the incoming fuel/air
mixture away from the plug element. When replacing the
plug, be sure to replace it with another Evolution 2- or
4-cycle 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.
NOTICE:
Do not attach the glow driver yet.
Step 3.
The high-speed needle valve should be turned
open 2-turns from closed for the initial first start.
Step 4.
With the throttle fully open, place your thumb
over the carburetor or the exhaust outlet of the
muffler and flip the prop clockwise through 6
complete revolutions, thus priming the engine.
Step 5.
Close the throttle to the idle position and have a
helper hold your airplane.
If you are planning to use a tuned exhaust system then
we highly recommend the use of either of the following

glow plugs.
