Support Equipment
The following items are not included with your Zenoah
engine but are necessary for operation.
Fuel—Mix gasoline and 2-stroke gas compatible oil at a
mixing ratio of 25–40:1.
Note: Be sure to use a gasoline-resistant fuel tubing
(do not use any silicone rubber tube). Never use any
alcohol fuel or alcohol-added fuel as this will damage
the rubber part of the carburetor.
Manual or Electric Starter—For manual starts, a chicken
stick is highly recommended. Never use your fingers to start
any model engine as you could be injured. If you must hand-
start a gasoline engine, be sure to protect your hand with
a heavily padded glove. There are a variety of heavy-duty
electric starters on the market that can be used.
