I have heard several times on this board that the stock jetting for an XPL is rich. I have a brand new boat and would like to fine tune it after break in. Once the warranty is expired I will probably put a PPG stage 1 kit on it, but until then I will keep everything stock.
My question to the group is where is the stock jetting rich - low speed, high speed, or both? Can I correct by just turning the high (I have heard hard to access) and low adjustment screws, or will I need to change internal jets/needle & seat assemblies/pop off springs etc? Does turning in the adjustment screws (clockwise) lean the mixture? Does anyone have an estimate on how much to turn the screws? I will be using Amoco 93 octane super unleaded which I have heard tends to burn a little lean.
Thanks.
