13 is good at idle with these engines. I have tried going leaner to 14 on mine and it did not like it. The jets you have listed should work fine. If you aim for 14 at cruise, it will get bucky and bumbly. You will see what I mean.
Blue smoke is not a good thing, are you sure it is not black? That carb is a double pumper and can throw a lot of fuel in with the double accelerator pumps.
I know your using it for the future turbo setup. Normally, that would be too much carb to use for a N/A engine. As it has manual secondaries.
