The orifice is at the end of the valve, the little precisely drilled hole
that lets the gas into the venturi. Since it's always been on natural gas
though I guess that's not the problem..maybe the burners just need a good
cleaning, my grill gets nasty every year and burns yellow till the burners
get wire brushed and all the little rusty holes in them poked open again.

As far as I know the grill has always been run on natural gas, so I
presume the regulator and valve were designed for that. Where is the
orifice located -- in the valve/regulator somewhere?
