advance & carbon was me&'73

Just a couple of things to add to D2's post:

I thought the same thing when I read this, but isn't it being advanced which 
induces run-on?

Also, I think the big problem is despite the raise in CR, it makes for 
uneven "hot spots" in the chamber. Kind of like when there is left over 
"flash". Not a good thing.
