FEATURES
Advanced Bi-Metallic Liner. This process uses a double layer of
plating material rather than one thick layer. This helps the metal
to bond to the cylinder and is more durable. Also, the plating
process is more consistent, resulting in a more precise fit between
piston and sleeve for better compression, longer life.
Side exhaust
E-3071 Power Box muffler with squared-off shape enables it to fit
into a variety of cowls
40K carburetor with rear angled needle valve for added safety
Ball bearing-supported crankshaft
