Cylinder Porting for Small Two-Stroke Cycle Engines 710601

A new method has been developed to die cast porting in cylinders for two-stroke cycle engines. Machining the ports has been eliminated as well as special deburring of port edges inside the cylinder.
This cylinder has reduced the amount of distortion due to heat, permitting tighter piston fits which, in turn, improve starting and idling characteristics of the piston-valved engine.
