hey settings i have used on my hyper 8 port are

3 turns bottom 1.75 open high. for some reason i have it running quite lean as far as stock settings go but it still is running rich. i can close it a little more. ususally top end on an 8 port should be between 2 to 3 turns open, i dont know about the 4 port. my engine idles really well. will run all day without stalling. it even runs upside down without stalling !
