Throat opening

[daveman92789]

Is it possible for the throat opening from the firebox to the CC to be too large? If so what would the drawbacks be of too large?

I assume it's better for it to be too large than too small. I have a pecos and based on calculators online the throat should be 51in² & its currently 36in². I want to cut it out more so the firebox doesn't trap so much heat.

Thoughts?

Offsets tend to run hot already. Just making the chamber hotter would be a problem IMO.

Is your cooker not working correctly? No reason to fix something not broken.

No it works fine you can just tell that hot gasses get trapped in the firebox.

The fb/cc opening is 8.25"x4.25" seems a little small. FB is 20" diameter x 20" long. CC is 20" diameter x 40" long. Stack is 5" diameter x 28" long.
