An engine is nothing more than an air pump. You draw air in and push air out, in between the in and out you have a controlled explosion that powers that pump. Now this of course is simplified in what it does, but the better you can move the air in and out the more power you can get.
This is what we all want to do to some point or another, produce more power. But we need to do it in proven and tested ways. Find a book on tuning a two stroke and then you can squeeze out ever last ounce of power you want to or at least try to.
