It may seem the riser is pushing but it’s the downstream cooling effect that is pulling (“contraction”) the flame to behave the way it does in the J-tube. Even with the addition of the by-pass that is used to draw the combustion first horizontal then vertical up then vertical down to “PRIME” the system... to heat it up to establish a pull.

I wanted to compliment you on your brick oven build.
Rereading this thread I realized no one has commented on it! Outstanding Job, it looks great!
Rather than continuing debating pushing or pulling.
I, like our friend Thomas T , am happy to wait for your build.
Thomas Edison was looked at like he was crazy when he talked about electricity.
If your ideas pan out to be a "face palm moment" then I am looking forward to hearing all about it!
If they don't work out as planned then you know what to fall back on.
We really are just trying to help, not give you a hard time.
Keep us posted as you find the time! .
