Homelite Super XLAO not oiling?

Hello, I have a Homelite Super XL AO, model 10045B that is NOT oiling.
I have replaced auto oiler with a NOS oiler. With bar and chain removed, and oil port cleaned, I have pressed manual oiler for quite awhile, and run the saw to see if auto oiler workes, but it will only blow a small bubble of oil and air. (very small amount) Any advice would be appreaciated.
