I start my engines on a fast idle setting, and leave them at that for 20 seconds or so to make sure they are settled before doing anything to them. With my two strokes, especially for their first flight of the day, they seem to like to have their throat cleared, and I have found the most reliable way to do this is to run at a fast idle.

Once that is done, then I open up slowly and run at full for a few seconds, then down to full idle. Then it is full again for the nose up check, then go fly .
