It is easy to fix the platter rubbing on the silver part of the front by simply bending the top of the silver part down with your fingers. It is just thin aluminum. I just stuck my fingers of both hands on the silver part that is above the letter "B" in Blackstone and under the platter and pressed it down. My platter may not be 100% level, maybe 1/8 of an inch difference from side to side, but it no longer rubs and its not like the slight un levelness of the platter is making my cheese run off or anything. And as it rotates it is always the same height over the burner. On my second Blackstone the igniter works OK after it clears what I am guessing is air in the line, out.
Lord Bacon, I just re read your orginal post again and the burner control being bent is what was wrong with my first Blackstone, actually the whole chassis was bent and the platter had an inch of difference from side to side. Blackstone quickley sent a replacement minus the stones, legs and top at no charge. They didn't even want the bad one back
