Sounds like a hotspot. A small offset will have a significant hotspot - requiring a larger baffle between the firebox and smoke chamber.
Even on my big Lang... will run very hot - because the firebox is partially notched into the smoke chamber.
The first foot nearest to the firebox... is my chicken chamber.
Suggest running a biscuit test and verify your temperature range shown in this thread.
Bacon should be capitalized as a pronoun for pork!
