I'm not familiar with your engine. But, in general, 2-cycle (or 2-stroke) engines have no oil in the crankcase. The gas-oil-air mixture enters the large crankcase first, which is when it can lube all the moving parts. Then, as the piston moves downward, the crankcase (which is sealed via check valves) gets compressed. This pressurized gas-oil-air mixture is then fed into the cylinder when the inlet port opens. The inlet port (located on the side of the cylinder, as is the exhaust port) opens when the piston moves downward. You see, there are no actuated valves in a 2-stroke engine. The piston, as it moves up and down, opens and closes the intake and exhaust ports which are in the sides of the cylinder. OK, so this pressurized mixture moves into the cylinder, which also pushes out most of the exhaust gases. Then, the piston moves upward, closing off the intake & exhaust ports and compresses the gas-oil-air mixture. The spark plug then ignites the mixture for power. The piston moves downward and the pressurized exhaust gases start to exit when the piston moves downward enough to open the exhaust port. I know this is a bit wordy, but 2-stroke engines are really cool. They have fewer moving parts. They're light weight. The produce more power as they fire on every engine revolution rather than every other like a 4-cycle engine. Good luck fishing. Bri
