Ran with the 4150 carb

I'm sure you are correct.

That's was my point, most people are satisfied with that. I am not. Just because your running a big carb you shouldn't settle for dumping excessive fuel in the motor under cruise. I don't care about the mileage as much as washing oil off the cylinder walls and shortening the life of the engine. If I would have just left the 1050 alone it ran fine. But when it's cruising around at 11.5-12.1 afr I knew I could improve upon it. It took work but I got it there. Runs good, it's clean, and the mileage is a bonus!

It's easy to tune for wot, its drivability that takes some work

Point well taken.
