Looking into the differences between these carbs and wondering if anyone has experienced a noticeable performance change between the two. Seems like whenever EPA is attached to something there will be a compromise of some sort. After viewing the parts diagram of both models it seems like there are a few things not the same. The high/low screws on the hd-12 are different with what appears to be a provision to work with the limiting caps although I cannot tell if the dimensions are the same between the hd-12 and hd-6 screws. More concerning is the two jets. First is an air jet( hd12-503943601/ hd6-503800401) and second is another jet( hd12-537003301/ hd6-503688201). Would it be worth changing these two jets on a hd-12 carb if this is possible. The carb will be used on a woodsported and decked 372 OE. Thanks in advance and all the best
