The orifice diameters do NOT scale with pressure drop!!!! As I said, use the chart, extrapolate for 6 vs 7 and that difference works out to an optimal size a couple mils (.001") large than you have. The drill that would enlarge your holes by that small an amount does not exist. SO DO NOT DRILL THEM. You could use a wooden toothpick I suppose. But it sounds like you've already decided on a new grill.
I can see the picture fine. I am "surprised" by the spacing of the holes, and hence the design of the burner, but given that, the flame height looks reasonable. And it could be an optical illusion thing, but the flame does not look fully developed circumstantially on the inner burner??? Like there's no blue flame in the front, away from the feed? If that is true, yes there is a gas problem.
I had no idea this grill with two burners with two orifices only had a single control knob. When the inner burner goes off, but then comes back on, it's because the gas is building up until it "explodes" into lighting again. That is not all that safe. It could be that if you had 7 inchWC instead of 6 that "feature" may not be as prominent or gone completely. Still, commercial gas appliances should be designed to have a greater operating range than that!...But the inside burner TURNS OFF completely at a certain point! And sometimes turns back on as you reverse...

I normally suggest to people on this forum to "use it up and wear it out"...heck, it's the way my Folks raised me. But this Fuego sounds like a poorly designed product to me. If you have the resources to replace it with a Weber or something reputable, that's certainly my suggestion.
Sounds good. I certainly use a lot of work-arounds myself. But how hot can it get now when keeping the lid closed? Not enough heat is what started your concern with this thread, right?Was thinking the same that the 6 is too low for burner 2 to be stable but I can avoid the problem by never allowing it to go off. Noting a little bit beyond 12:00 the knob turns it off. I could also make a “stop” to limit the knob’s range.
