There are different orifices for natural gas and for propane, you need to
change them to get it working correctly. Check with whomever made your grill
if you converted it from propane to natural gas and didn't change them at
the time.

I'm wondering if I've got the wrong venturi, though. Even with the air
supply all the way open, the flame is really yellow when it's on high.
Is that normal? Does natural gas require a different venturi than
propane?
