I tried but its super hard trying to hold the phone,flash light and move the power valve rod at the same time lol...Well heres the running video and looks like everything is working like it should but not 100% sure as I never saw one moving while running lol..
Next step is to put everything back together the pull the carb/reed cage and check reeds..Then i'll pull the carb bowl off and check jets...What it feels like is its loading up pretty good past 1/2 throttle and you can hear it in the video,well I hope you can..
Heres the running video----> https://www.youtube.com/watch?v=rNtzX-MUjho ..

funny...one of the 1st things I noticed in your 1st vid, was how much black spooge was around the exhaust outlet/cylinder, like it was running extremely rich.
Definitely pull the carb and find out exactly what your current jetting is...Main, Pilot,
look at the needle closely, and post the numbers and letters that're stamped into it, so we know which needle is in there, and what position the needle clip is in too.
it also "looked" like your governor rod seal was leaking too...the rod you were pulling in and out in the 1st vid.

+1. I had similar symptoms mine was a bad coil. Get your carb cleaned up check your jetting and start testing electronics. I believe it was sandblaster who did a write up about testing and specs that's what got me pointed in the right direction
