Honda racer, thanks for the input, you are 100% on the money. I looked at this last night, the door seal is not tight was creosoted up and the little rubber flapper had dry rotted a 1/4" crack in the bend. I replaced the door seal with a 5/8" seal which was too small but got me going and ordered a one inch door seal online last night along with a new flapper. The stove is currently working properly with no runaway temps. I also found a manual online which always helps.
The stove is a Woodmaster 4400 Heavy Duty model. The more I use this the more I like it.
To help pull the door tight for now, I slid some lock washers over the door bar for a spacer that rubs or contacts with the inner wall. In an emergency with a leaking seal, this might be something a person could do until there parts arrived.
