Fuel
This engine requires a mix of 20:1 gas to
oil lubricant ratio for break-in and normal
operation.
The needle bearing at the bottom end of the
conrod depends upon this lubricant ratio to
operate properly.
Fuel Delivery System
It is very important to properly construct your fuel supply system to the engine to avoid
operating problems. Our experience has shown that many seemingly engine-related operating
problems are in fact fuel delivery problems, not engine-related problems.
fuel filtering - Because of the incredibly small
amount of fuel that is being used by this
engine, filtration of the fuel is mandatory in two
different spots in the system:
1. Between the fuel jug and the tank.
2. Within the fuel tank itself (with a sintered
plastic filter clunk EVOA121).
One of these filter clunks is included with
your engine.
Tank location - Because there is a crankcase
pressure-driven pump on the carburetor, tank
location is less critical than with a muffler
pressure-driven system; however, it is still
good practice to mount the fuel tank in line
with the carburetor, and as close to the rear of
the engine as possible.
Care taken in mounting the tank as
described will provide trouble free operations
in all flight attitudes.
Tank Capacity– Choose a tank between 6–10
oz (180–300 mL). These tanks will yield 18
minutes (for the smaller tank) to 30 minutes
(for the larger tank) of full throttle flying time.
Do not use leaner than a 20:1 gas/oil ratio or the
warranty on your engine will be voided.
To properly mix the fuel, add 6.75 oz of high
quality 2-stroke oil to one gallon (or 53 mL of
oil to one liter) of 87–93 octane fuel.
• Ensure you use a tank stopper made for use
with gasoline and/or smoke oil.
• We suggest a three-line tank system; one
for the line to the carburetor with the clunk
attached internally, one for the vent line
to the atmosphere, and one dedicated to
fueling/defueling the tank.

• Ensure you use the included sintered plastic
filter clunk inside the fuel tank.
• Ensure there is a good seal system for
the dedicated fueling/defueling line. We
recommend the HAN116 Fuel Filler Assembly.
