Open both the high and low about 1-3/4 turns out.Then start adjusting.Open or close the low needle[one closest to the engine]until you get a good idle.Open it up and set the high needle.
Then blip the throttle from low to high until it wont transition good.Then open needle about 1/8th turn.Then adjust the high again.Youll be close enough for that engine.Its basiclly the same as a quadra or any industrial engine as thats what most started as anyway.
