Attaching the Propeller and Spinner
Attaching the Fuel Lines
Using medium silicone fuel tubing, attach the fuel tank’s
clunk line to the fuel nipple. This line will supply fuel to
the engine. Attach the vent line to the muffler pressure
nipple. This line pressurizes the fuel tank with the muffler
pressure, creating consistent fuel flow, regardless of the
airplane’s attitude.
Starting the Evolution Engine
Fuel
The Evolution engine comes baseline adjusted from the
factory. We recommend using high-quality Cool Power
Omega or Power Master fuels containing 5 to 10% 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 valve to compensate for the
differences in fuel.
Glow Plug
The Evolution engine comes with a specially designed
“Super Plug”. 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 2–4 stroke Super Plug (EVOGP1).
Starting the Engine
Step 1. Fill the tank with the above-mentioned 5 or
10% 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. Place your thumb over the venturi and flip the
prop counterclockwise through 6–10 complete
revolutions, thus priming the engine. Have a
helper hold your airplane.
Step 4. Attach the glow driver.
Step 5. Turn the engine over using an electric starter.
The engine should fire within seconds of applying
the starter.
Step 6. Remove the glow driver.
Step 7. Allow the engine to run for 30 seconds. And then
adjust the needle valve for your desired ground rpm. We
suggest you set the needle valve so the engine is running
at a fast 4-cycle, if you are using the engine for stunt and
sport applications.
Note: We have found that the best rpm to start with for
this engine is to set the needle so the ground rpm is
8200–8500. This will provide a solid 4-stroking style
run with a 2–4 break when needed. Pick the appropriate
prop to match the application and airplane. A 5–6 pitch
prop at these rpms will yield a 5.2–5.4 second lap time
on 65- to 67-foot lines. We recommend as a starting
point the mid-sized venturi .181 in (4.6mm) and a
12 x 6 to 13 x 4.5 two-blade propeller.
Securely tighten the prop nut using an adjustable wrench.
