2 stroke back pressure?

Just read a post reply (TERMANATER) that discussed putting a 2 stroke in a tank and being careful about the depth of water. According to the discussion the caution relates to proper back pressure required by 2 stroke engines. I have always been careful about tank depth but only as it relates to proper use of the water pump. I'm now concerned about my recent fishing trips in very low water where I elevated the trim to clear bottom and only being concerned that the motor was peeing properly. Did I miss read the post reply about back a pressure requirement. If so, can a simple reply educate me?

I'm going to guess the post was in regards to setting the idle speed. 2 stroke engines are very dependant on backpressure at idle. If you set up an old school 2 stroke outboard on a hose, chances are it will idle very low when you put it in the water from the added backpressure. It doesnt hurt them to not have enough backpressure, but when setting one up you must do it under the conditions it will be run in.
