  "textContent": "This invention concerns a two-stroke cycle engine, more specially it concerns a two-stroke cycle engine using a preceding air-layer for scavenging. It has a scavenger passage (109d) connected to a branching scavenger passage (109d) opened to said scavenging port (9a). The engine has a connecting passage to link the air passage (10b) and the fuel passage (15) so that negative pressure in the air passage (10b) forces the fuel-air mixture in the fuel passage (15) into said air passage (10b). Further, the engine according to this invention has a removable guide (501) with a surface forming a curved smooth channel which is attachable to the scavenger passage (109d) in the crankcase (5) from the mounting surface, and forms a portion of said scavenger passage (109d) with the curved channel. The blow-up angle of the scavenger passage (109d) varies along the circumferential direction of the cylinder (2). The crankcase (5) is configured in such a way that the front and rear portions, which are separated by a block, and a scavenger passage (109d) is provided inside both said front and rear portions of said crankcase (5), and the cylinder (2). The air cleaner (1001) has two air passages (1061, 1071) running from it in parallel, the first one (1061) is connected to said air passage (10b), and the second one (1071) is connected to the air inlet of the carburetor (12) to provide air for the fuel passage (15), and a choke valve (1201) on the air cleaner (1001) is provided to open and close both of the first and second air passages (1061, 1071).",
