I am restoring a silver b that I picked up and was wanting to know how to adjust the air mixture on the burners. I lit it and had alot of orange flame. The burners are good and I have a full tank of gas. What should the flame look like? Thanks

There's one adjustment screw per burner, located near the spider screen. If you have the older burners, you'd have to remove the plastic spider screen first to see it.

I usually go for a flame height of 1-1.5" - the flame should be blue with an occasional orange tip.

I think there is something else wrong with the burners. The flame should be blue with yellow tips. I have seen them burn orange just after cleaning or if debris falls on them, but after it burns off, they should go back to blue/yellow.

If you want to mess with adjusting the airflow, look at the burner venturi and if it wide open of almost shut, then adjust them closer to being half open and go from there.

Yep flames should be around an inch in length and mostly blue with little/no yellow at the tips.

This video was helpful when I was adjusting the air shutters on my new burners:

Weber used to have a help page on their site about adjusting the air shutters too but looks like it might be down or dead:

I like the quick burner removal design on that grill.

Those air shutters don't magically go out of adjustment. If you have a grill running normally and than it begins to burn "dirty" adjustment is not the issue. Look to gas supply, cleanliness, and pressures NOT readjustment.

Yah, my guess is the burners need cleaning or a chance to burn off contamination. Other issue could just be the burners are shot and the holes are bigger and connected due to corrosion between them.
