    the basic engine parts are pretty much the same, a 2 stroke is missing a few things like an oil pump, oil pan and dip stick.
    about the only thing I can think of is a 2 stroke is short one valve.
    Now you’ve got me wanting to tear apart my chain saw!

    Mags can be found in both.
    reed valves , rotory valves , cylender ports , oil injectors are common in two strokes
    OTR truck engines have oil pans and oil pumps and fuel injectors and no mag.
