Fish Cooker Question??

I have a 2 burner fish cooker that is home made. My grandfather gave it to me a few months ago. It had been sitting in storage for a long time. I got it home cleaned it up, painted it, and put a new regulator on it. I lit the first burner and it fired off great, looked and sounded like a blow torch. I lit the second burner and the flame looked like an extra tall flame from a bic lighter. The burners are built out of one pice of half inch pipe with 2 holes drilled in it. One hole for each burner. The burner itself is a piece of maybe 2 inch pipe welded to the half inch. The burners have a ball valve between them. I am wondering if I can replace the ball valve with a regulator and make the second burner work like it should. The cooker has sentimental value because I got it from my grandfather and because of the man who built it for him. Any advice would be appreciated.

I wished I could help. You have reminded me of my Paw Pa's butane rig. He was an expert with that rig. Before he had it built "in the oil feild" out of sucker rod, he cooked over an open wood fire. It was my job to gather the wood. He knew the fire was hot enough just by looking at the grease.
