Another TQ question

I have a TQ on which I recently replaced the fuel bowl with an NOS one. I don't know what main metering jets it came with. I am using the same metering rods as I was using before, so this may well be a mix-n-match situation as far as main metering jets and rods are concerned.

The engine runs OK at idle, but starves for fuel on the primary high-speed circuit. I have verified that the step-up piston rack is engaged with and lifting both of the metering rods. Do you think I should lengthen the step-up piston rod adjustment because the (likely) mix-n-match jets and rods aren't letting enough fuel through, or look for some other problem instead?

Is there anything else that you think I should check? Thanks again. I really do appreciate your help.
