The wilsons tapered 4 hole matched fairly well to the carb pad opening and I was following their direction with the removal of the clover leaf and putting their spacer on top. The straight 4 hole obviously covers more of the carb pad, so will see how this works out. May just be a common issue with this intake and I found it with the red dye in the fuel. Gonna call Brodix Monday and see what they say about a turtle in this intake just for curiosity.
