Fuel
This engine requires a mix of 32:1 gas to oil
ratio for break-in and normal operation.
To properly mix the fuel, add 4.0 oz of high
quality 2-stroke oil to one gallon (or 32 mL of oil
to one liter) of 87–93 octane fuel.
Fuel Delivery System
Fuel tank
Filter clunk
It is very important to properly construct your
fuel supply system to avoid operating problems.
Our experience has shown that many seemingly
engine related operating problems are in fact
fuel delivery problems.
Fuel Filtering
We recommend fi ltering the fuel at two locations:
1. Between the fuel jug and the airplane fuel
tank.
2. Within the fuel tank itself (with the included
Sintered Plastic Filter Clunk (EVOA121)).
Tank Choice and Construction
Choose a tank with at least 24 oz (700mL)
capacity. A 24 oz tank will yield 12 minutes of
fl ying time. This engine has a fuel consumption
rate of approximately 2.2 oz/min (65 mL/min)
at full throttle.
We tested primarily with Red Line two-stroke oil.
Other high-quality two-stroke oils will also work
well.
Mixtures as rich as 25:1 are acceptable.
