I'm thinking the same thing. If intakes are too far open, exhaust too small... pressure, like electricity, takes the path of least resistance- expanding hot air from the fire escapes easier thru the lager opening (intakes) and sucks fresh air in thru the exhaust port.
That's my theory at least.
Now THAT would be a true reverse flow cooker!
