You can press "print screen" on your keyboard, then open "MS PAINT" (just type 'paint' into the start menu) and Then press PASTE
It will paste a copy of the screen shot you take. You can save the file as a .JPG and upload it. Or continue using youtube its fine. Im just giving you options whatever is easier.
Here is your plugs please verify I have them label correctly
#2 looks the best. See the top of the electrode is nice and clean. The plug isn't stained brown. A small dark mark is normal its barely visible. A tiny bit of oil is normal.
#6 is the worse, filthy. Tiny flecks of hard carbon appear baked into the center white. Either due to handling or engine sitting carbon buildup getting hard then flaking off.
This is why we don't use iridiums right off the rip. Start with cheap plugs. Get many run time and mileage on the engine and oil changes and fully tuned. Then switch to iridium at last.
If the engine sat a while it may have poor valve sealing which will be demonstrated by compression test. It is odd that #2 has a good clean white plug but disabling that cylinder makes the engine go so lean. Could you have accidently wired 2 and 8 together so that disabling one of them causes both of them to turn off? I think you may be looking at something in the wiring. But I am getting ahead of myself we need a compression test just for general well being anyways.
