Wondering if anyone else has this particular situation. I did a search but could not find where anyone mentioned this. The burner seems "very loose" Sort of floppy. When I roll the oven out across the patio, the burner always flops toward the inside. I have to get something long and skinny to get the burner upright or the ignitor won't light. The burner seems to work well once I get it upright, but I tried to find a way to tighten it, but was unable to do so. Is this normal?
