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.it takes a bit of practice to get the fuel mixture right. Make sure you have a good low pressure reserve (accumulator) or you will have trouble getting the engine to run reliably. They do not like running directly off a regulator.
