Thanks KTL, that helps. It certainly sounds like you know more about the inner workings of a carb than I do.
I wasn't planning on lowering my floats to adjust the AFR, but I was wondering where the right place in the window (PMOs) is. You even said 'full enough, but not too full'.
Do you think being right at the dot is too full. I was wondering if I was too full.
That was kind of my original question.

I understand the AFR and running that rich is not supposed to be good for the cylinder walls. I have read that the ideal AFR for carbs is about 12.5. Mine won't run properly at that ratio.
So I have to richen it up.

I think my rings are pretty worn (130,000 miles) so that might be where my rich readings are coming from.
I have 190 air correctors and 135 mains.
What would you do? Go bigger on the correctors or smaller on the mains?
Or leave it alone and it is what it is.
