Vintage Technics SL-1300 poltergeist--help!

Unpredictable auto-return problem shown in 25 sec .mov file publicly shared from my Microsoft OneDrive.

Shop has tried fixing twice, still a problem. They have tried cleaning and lubricating what the believe is relevant. I am searching for guidance / specific input as to what the problem is as well as new shops to try probably.  I'm in Indianapolis but not reluctant to take it where needed.  Otherwise this old friend is in great shape (dusty from having been stored in a seldom cleaned room). Before this developed, new Grado added and took off the auxiliary screw-in tonearm weight, set 1.5gm VTF.

Thanks,

Warren

Thanks!  He really never addresses weird channel (or whatever on that plastic gear/cog wheel/whatever...).  I need to go back further than where it started playing for me.  I'd like to see what interacts with that channel, if anything.  There must be something--else why have it molded in like that?  In other words, when he is ready to button it up there appears to be nothing that is going to touch it except on the side that becomes hidden during reassembly.

I can't understand why that "channel" exists when I see nothing that interacts with it.  At first, I thought it's there simply to provide better strength or rigidity but that wouldn't dictate the shape of that...???

Mine began acting up and repair attempts weren’t successful. Being someone who doesn’t love the automatic turntables, I gutted the automatic parts, set it up as a manual, and it’s phenomenal—basically an SL-1200 in functionality. New Ortofon cartridge was a big help too. Sound and function are flawless now for four years.

Is the onset of the malfunction temporally related to when you removed the counterweight?

And yes, I think the channel could be there to enhance structural rigidity.
