Can you use them in the same way as a 2 stroke.

Someone has told me you can only cut in certain ways ???? as opposed
to a 2 stroke.

They will cut in any direction as the crankshaft has an agitator on it that
throws the oil in the correct direction when inverted.
Also they have a diaphragm carb that uses crankcase pressure to deliver
fuel.
