Hi George (and anyone else who's knowledgeable),

One thing that is not obvious to me is why LOP operation seems to be
predicated on having a very balanced fuel/air mixture to all the cylinders,
i.e. why are GAMIjectors necessary? Why can carburated or non-GAMI'd engines
run ROP (presumably also with poor mixture distribution) but not LOP? What
is it that causes them to run rougher LOP than ROP? Again, I'm presuming
that they have poor mixture distribution in both cases, but it seems like
they'd still get the advantages of LOP operation (better pressure peak
timing, cooler temps, cleaner) if there weren't another factor involved
causing the roughness.

I'm obviously missing something.

Thanks!
