OK I always had Webbers so I new how to adjust them. Now I have Dells and how do you adjust them.
Everyone says its like adjusting weber, but they look different. The red circle on the weber is the Air Bypass adjusting screw, while on the Dells it has what looks like a vacuum nipple. The green circle both seem to be the mixture screw? The Dells are recessed and it is hard to get a screw driver in.
