Exhaust stink

[CSH-HQ]

Since there is more than one posssible answer, it is vague.  Some fuels you 
cna go way rich and not have a problem.  Some others just a tad, and other 
takes more, to get the smell.
  If some donates a infra-red gas analyzer to gas bench to CSH, HQ I'll 
galdly report back with hard numbers <g>.
