PS is there a port that is blocked that l missed or something.

Answer
Check the head bolt torque, 200 inch pounds.  The head bolts are prone to loosening.

I'd bet the problem is still in the carb.  I've had to clean some of those carbs several times before they worked correctly.

Did you blow compressed air through the holes?  Was there any varnish in the carb bowl?

Let me know.
