INSTALLATION OF THE ENGINE AND FUEL TANK
Use the engine mount supplied with the
engine to install the engine in the model.
Decide the installing position. Any direction
will do.
As short as possible
Set the fuel tank position so that carburetor
center line may locate at 1/3 from the tank
top when the model is placed horizontal.
Locate the fuel tank as close as to the
carburetor, or the fuel level difference will
affect the engine running when the model is
upward or downward.
