And has two holes about 1-1/8" anyway one that I saw one at the home store that is close to 5-7/8" dia with nothe holes ,do you think I could choke this stove down somemore?
You know Smithy, my personnal opinion for MPD is if the stove is as air tight as possible (principally at the lower places we already talked about), a MPD would not be necessary. Plus base heaters have a so long gasses path to slow down the draft...
But we can say all we want, in the past they didn't have the sealers we have now like the rope gaskets. A metal on metal seal will never be and stay as air tight as a gasketted one. The new high end stoves don't even use cement when assembling cast iron parts. The lazer cut are so precise that they can place rope gaskets and seal the parts for ever. Much more resistant than cement...and air tight.
When I made the first fires in the Bride, I had to close the MPD all the way to try to lower the fire. With the stove much more air tight, I can control the burning rate and leave the MPD just a little angled. Plus as said before the mica stay cleaner when the MPD is more opened.
I think that it's better to lower the combustion rate from primary air entering in the stove than trying to choke the draft with a MPD
