The intake charge comes from the carb and goes into the crankcase first under the piston. As the piston comes back down and closes off the intake it pushes the charge up from the crankcase into the lower transfers. Then exit the upper transfers above the piston into the combustion camber to be burnt.Look at the base of the cylinder, see the gasket? Now where the cutout is for the transfer ports, it's solid= no opening! How the F... is oil going to get under the rings? Every cylinder I have ever seen has openings that the intake charge goes into the crankcase thus supplying oil to the crank. Now pay attention this time- please explain how oil gets to the crank in this motor. The diagram is great but does not apply to this motor because the intake is not connected with the crankcase.....
Looks to me that its a gasket for a different saw but as stated it doesn't matter as long as it is sealed.
