I recently bought a Echo PB-755 Backpack Blower to blow leaves in my
yard.

I am very puzzled by it. It is a 2 stroke engine. Takes 50:1 oil.

There is no separate tank/port/opening for engine oil.

The manual has not a single word mention of engine oil (like 10w30 or
whatever).

So, all indications are that this engine needs no oil.

I can hardly believe this as all gas engines I have seen so far needed
engine oil.

Is my conclusion that the engine needs no oil, correct?

RTFM. Yes, it needs oil. The oil is added to the gas.

I actually did say that oil is added to gas. I did not miss it. I am
surprised that there is no separate oil system, to oil all the moving
parts. How are they lubricated?

I see that you have the explanation how they work. I apologize for
the 'rtfm' comment. Thinking back I was in the same position when
someone told me that diesel engines don't have spark plugs...well, not
after they are running at least.
