problem is one of the burners works perfect, the other one just dont want to burn properly
ive taken it all apart and cleaned everything out with carburetor spray and put it all back together but the one burner just won't make a proper flame. I tried adjusting the vent and blowing everything out out with compressed air, still won't burn right.
I use the one burner but would really like both to work properly
anyone been through anything like this

You need to run a pipe cleaner through it. Blowing it out won’t get a spider web/nest out of there. Those critters can plug one of these up overnight.

NSB is right. Insects are notorious for clogging up small spaces. You probably need a small needle to make sure the hole in the gas jet is completely clear. Close the air vent almost all the way. If it lights, open it slowly until you get a good flame. If it is open too much in the beginning, it may not light.

BINGO! Most likely problem. Either the orifice or valve?

I have one of those for melting lead and emergency cooking should we loose power.
