Ran fire rope around the inside of the door. Stopped a big exhaust leak just above the latch and also an intake leak at the bottom of the door.
and, raised the fire basket 2" above the bottom. MUCH easier to dump ash accumulation without removing the basket.
A test run yesterday gained appx. 35*-40* inside the smoke chamber and held 240*-250* with not much fuel in the fire box.
Made me happy!
