I’m using a regulator I bought at Lowe’s, it’s a grill regulator with two hoses, one is plugged.

Need some help troubleshooting. The burner I made is basically a carbon copy of this one here. I used a .035” welding tip, and from the brass I connected a 10ft propane hose rated for home use I believe, and from there I have a hose to connect to my 5 gallon propane tank. Is this a pressure issue? Is my regulator not giving enough propane or is this an air intake issue? It sputters and doesn’t roar like the others I’ve seen.
