Does anyone have one of these portable grills, if so could you please school me in their operation. I bought the premium instead of the silver because I liked the idea that the carrying handle would keep the lid on during transpot and when it is folded back it doubles for a place to put the lid, very similar to how the master touch stores the lid. Nice little grill but I can't get any heat out of mine and if I put the lid on the coals will eventualy go out or almost at least. I blame it on the air intake vent location. The air intake vents on the premium are above the charcoal grate on the sides but on the silver it is on the bottom (where it should be). Never heard of this problem until I had one. Am I doing something wrong during operation or is this a flaw in webers design. I contacted weber and of course they have never heard of this problem before. I have seen on the net where people instal the sjs air intake on the bottom of the bowl and it works great after that. I have tried to find one the vents but I live north of the border and cannot find one anywhere here to get them. I have found them in the US but with the shipping it cost more than just going out and buying a new sjs. Any help would be appreciated.
