All 2 strokes are not designed alike. The term "2stroke" refers to how
often the piston goes up/down per power stroke. Not how air or fuel is
fed to the cylinder. The crankcase of you little diesel 2 stroke is
designed like an outboard. A DD crankcase is designed like your
automobile engine's (assuming it's a 4 stroke).
A DD 2 stroke can't run without a blower.
