Those are some great tips, thanks. I decided to fire it up again last night without cleaning anything and it stayed lit all night with no issues. The flame on the main burner was consistent too, no flickering. I really believe my problems with the flame are due to a draft coming in the vent, maybe when the wind is blowing a certain direction. You ever hear of that being an issue? Either way, at least its working now and I don't smell propane anymore.
I'll leave it alone for now and if it starts acting up again, I'll clean the orifice.
