Smokes pretty bad at idle/under 2k

It's a rebuild engine.
It has 300 miles on it.

The smoking only started once I restabbed my timing. Previously I was running lean and it would make the turbo glow under low throttle. I restabbed and got the timing dead on.

Now it smokes under 2k rpm/while iding.
It's a blueish/white smoke. My exhaust tip is very black right now.
Once I start driving it will go away.

Here is one possible culprit. The Walbro fuel pump is killing my FPR's.

I have an inline fuel guage and it says I'm doing 45-50psi constant. I have swapped FPRs trying to fix it but it did nothing.

It almost sounds like the car is missing sparks sometimes during this smoking stage. It has a rough idle at this point.

It usually takes around 5-10 seconds for the smoke to start up once idling.

If I rev up to 2k it will go away.

I am going to swap spark plugs tonight but I doubt it will fix it for good.
Any thoughts?

It shouldn't be the turbo since I have already revised the feed and drain system to restrict the flow.

Give Kevin a call. I'm sure he'd be more than willing to help with the situation.
