Stratified scavenging two-cycle engine

A stratified scavenging two-cycle engine comprising:

• a piston;
• a cylinder block, containing a cylinder chamber in which said piston is disposed so as to be slidable;
• a crankcase, connected to said cylinder block and containing a crankcase chamber;
• a scavenging flow passage, having a scavenging port formed in a side wall of said cylinder block, for connecting said scavenging port and said crankcase chamber;
• a check valve;
• an air supply flow passage fluidly connected to said scavenging flow passage for supplying air through said check valve;
• a suction fitting;
• a carburetor for supplying mixture into said crankcase chamber via said suction fitting;
• and
• an air cleaner connected to said carburetor;
• wherein said carburetor is connected between said air cleaner and said suction fitting;
• wherein an air flow passage, forming a part of said air supply flow passage, and a mixture flow passage are formed in said carburetor at least generally in parallel with each other;
• wherein an air flow control valve is disposed in said air flow passage in said carburetor;
• wherein a mixture control valve is disposed in said mixture flow passage in said carburetor;
• wherein said suction fitting is connected between said carburetor and an outer face of said cylinder block;
• wherein an air flow passage, formed in said suction fitting, is fluidly connected to said air flow passage in said carburetor;
• and
• wherein a mixture flow passage, formed in said suction fitting, is fluidly connected to said mixture flow passage in said carburetor.
