Now that I know it fires, I want to play around with this a bit for sure. Along the way, I had read/been told that I could use a standard gas grill regulator. But I am stubborn and I was hoping to be accumulator free so I picked up a Fisher regulator that is rated for 1,400,000 BTU (R622-DFF). Based on volume, I had figured a minimum of 750,000 BTU and it was cheap enough so I figure I have plenty of volume. But, the downside to plenty of volume is that it wont starve that's for sure. After this weekend, I am more concerned about it running away before I get it dial in with the air.
I am sure it would also be easier if my fuel mixing valves would loosen up. As of now they are still stuck and this is 100% manual gas/air mixture control.
