I watched the AppliancePro video and ordered the replacement ignitor/orifice assembly which showed up the next day. Changed out the ignitor/orifice tube assembly as shown in the video and reassembled the range, and so far the burner works just fine. I did swap out the orifice in that the new orifice seemed to be slightly smaller in diameter than the existing orifice. For people not used to working on appliances, would suggest taking photos before removing all screws, etc to remember where they go during reassembly. I also did the recommended procedure of spraying WD40 on all the screws two days before the ignitor/orifice tube assembly showed up and used a nut driver to loosen and tighten the screws a couple of times to free them up.
