The difference that proper air/fuel mixture makes.
I changed out the burner tubes in the propane grill. The first set of burners I got did not have adjustable air inlets. Ordered some different ones and the difference is surprising.
You want some more cool shit, get a manual regulator. You can get a lot more out of your typical gas grill. It will likely come at the expense of longevity due to shitty materials.
The choices they made in material for my grill are weird. All the big parts and supports are rust resistant. Every single screw is the cheapest, shittiest one they could find and immediately started rusting. Hope the dollar they saved is worth me never buying grills from them again.
Could be worse; at least fasteners are relatively easy to source upgraded corrosion-resistant replacements for.
It reminds me of my old Samsung front-load washing machine: when that failed, I took it apart. Every single metal internal part was pristine stainless steel, except for one: the "spider arm," which attaches the drum to the drive shaft. It was made out of some kind of ridiculous reactive pot metal that had corroded completely through and broke apart just after the warranty ended. It was the most shameless example of blatant planned obsolescence I've ever heard of, let alone experienced firsthand.
No. The old tubes were well used and worn. It was high time for new ones. Just the first set I ordered weren't adjustable, hence the messy yellow flame on the left. I ordered a proper set with adjustable air intakes and now I get a proper blue flame as seen on the right.
Only problem was mounting the sparkers. Had to get creative.
I just buy new ones every few years. The pipes just have 1 screw or clip holding them on and slide right out. And the replacement packs are fairly cheap. Around $15 for the 3 burner pipes and those little diverter channel things that connect them so they all light from 1 starter. And takes like 15 minutes to change it all out.
