In my opinion the 3" is too narrow, its not like a vacuum cleaner that sucks the smoke up so it is restricted there to start with.

Get some sticky tape and tape a cardboard false arch onto the front of the brick arch but lower than your steel lintel, light a fire and see how it goes.

Adding to the height of the flue wont help if it isnt drawing at this stage.

Ive been involved with building chimneys and remedying other ppls builds for a while, this shouldnt be too hard to fix.

If you don't want to add height to the flue then going to a larger diam. will increase the power of the draw. This might be a simple option and avoid any structural changes.

Thank you for all the replies. I got an 8" flue tile and placed it. After doing this I lit a medium sized newspaper fire inside the oven and nothing appeared to come out the front. Knowing two things, its loosely placed. no mortar and no insulation that it will draw better than what I had, especially once it is installed and insulated correctly.
I also chipped out the back 1/3 of the arch to increase the area/flow in that space too. This was very minor and took almost no time and it fixes all the things you all addressed and what I believed.
Great forum, great help. Thank you guys once again. I will post final build photos when this monster is done. (fingers crossed that it will be tomorrow evening, US, Central time...)

I make my inner arc higher than the other. 26.5cm for inner & 25 cm for the other

If I cut my WFO the inner arc (1) is higher than the other (2)
This is my WFO Opening, may be help for your next WFO

Doesn't this make it difficult to fit the door?

It doesn't make any difficult to fit the door, just tilt little bit the oven door, and it fit to the inner arc. Of course it's difficult if you hold the oven door vertically
