We didn't get any video on Friday of it running longer but I didn't notice the sound from the first video. My daughter noticed it more. I'll have her get some video next time. Went and picked up new plugs and fuel filter at lunch today. Hopefully, we will get another shot at it in a few days.

Oh and definitely not the same issue as yours. We don't have a flywheel cover! The prior owner said he might have some parts at his cabin in the mountains but I'm not holding my breath on getting anything.
