Setup for 750DP on this 408
Ok, here is some plugs out of my junker. In the bottom picture you can see the fuel ring. It's way too wide. Also, if you look at the area just about the fuel ring to just up to the tip, you can see I'm fat at cruise too.
So the fix is to reduce the main jets until the cruise is correct, and then check again for WOT. If the cruise is happy and it's still fat at WOT, then I will reduce the power valve channel restrictions to get WOT in shape.
