got a souped up cajun cooker and a big ole cast iron dutch over back in the summer. im having some issues with the little gate valve i think?
1.when you turn it open to make flame bigger it has no effect even though i can tell the stem is turning out of the body of the thing. maybe i need to replace it with a good ball valve?

2.when i turn the flame up its like its cutting in and out and the fuel air ratio is not right. i see the little deal on the bottom where the gas line comes in that has the adjustor but no matter which way i move it doesn't get any better till I put a piece of tape over one of the holes?
