Apperently no one at cens checks this kind of stuff... I was told it was 1.5 out from flush and i know if you run 1.5 in from flush the engine will overheat and drive you crazy and make you think you have a bad engine... Its very nice cen just igrones this post. There needle settings errors and not following through with sending me the parts that did not come with my reverse kit just pisses me off more then you can belive. Espcially since i have found the wrong needle settings on there site twice now and then you have also found it too...
