Yes. There are a few on our Blog site showing the flames reacting to the air shutter adjustment with different models of barbecue. I think this one is the easiest to see because we used a barbecue with a clean stainless tube burner that has 24K BTU's. The video showing the Weber does not have as dramatic a difference because the flames don't change so much with such a low BTU setting.http://www.grill-repair.com/blog/2014/adjust-air-shutter-on-bbq-grill-burner-for-proper-burning/
Let me know if you need assistance after looking at this one.
Flames should be just taller than one-inch and should only have a little yellow or white at the tip.
Contact us if you need assistance or if you're not positive.
