First video I looked at was specifically for an Ariens 17.5hp lawn tractor like mine. Guy did OK in the video except he line the coil magnets up with the coil and adjust the valves there. Put EVERYTHING back together after following this method and BOY DID IT NOT WORK. Tractor wouldn't turn over all the way.

Watched anther video and closed the exh valve and adjusted the int valve and turned over the engine where the int valve closed and exh opened and bingo! This good as new.

I guess what I am saying is that no matter how authoritative a video may seem, it might just be bogus just like all other advice. Going to go ride around on my lawn tractor now!

This guy cracks me up. https://www.youtube.com/@TarylFixesAll
