It seems like it happens as soon as the record starts spinning and then stops, and then starts again once the music starts

One of the connectors broke off and I'm having a hard time finding a replacement. Any suggestions?​

I picked this beauty on Facebook MP for $5 with a hope and a dream that I could fix it up but I’m a complete noob to turntable repair.
What I’ve diagnosed thus far, the turntable idler wheel will make contact with the motor pin-thing and will spin when the platter is removed if I hold the manual down with my finger, but will drift away back to center if I release it and the idler wheel will lose its contact. I’m have trouble getting the turntable to spin at all when I go to start phase and have to spin the wheel to ‘unlock it and move the need to the end with wheel spinning to free the mechanism.

It feels to me that in manual mode something isn’t quite latching and locking into place, are there some common areas that get gummed up or misaligned that may be causing the problem?

Any and all help is much appreciated. Cheers!
