Fit silencer parallel to crankshaft axis with screw-on filter (2) not pointing towards
propeller. The double intake silencer is available with either left or right hand side inlet
opening, to suit respective position.
With the silencer on a single carburetor engine, pay special attention when fitting, as
with an inclined silencer the intake situation is unsymmetrical, thus badly influencing
mixture distribution possibly leaning down one cylinder, leading to a rise of combus-
tion temperature and finally to piston seizure.
