What are some parts found in a 2 stroke engine, but not in a 4 stroke engine?

Question

Are magnetos found in 2 stroke, 4 stroke, or both??

Answer 1

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!

Answer 2

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.

Answer 3

A reed valve.
