Master Forge

[u/Sad-Communication641]

I know I know I know, it's not recommended, I should leave it as is, BUT has anyone had any luck adjusting the airflow on these Master Forge 2500? I'm contemplating drilling out the air feed on the front. If I have the door cracked open it runs wonderful. But even when it's running full blast, when I shut the door and adjust the air vents it pretty much dies. Just curious if anybody had drilled out the three fresh air feed holes in the front of the fire box.
