I don't know what connection I fixed, but I took 'er all the way apart and put 'er together, and I fixed it and now it's fine. Frustrating, but it works.
Hey, I can't find info anywhere online. Do you know what the cap in your grinder is? I have the same thing, 3/4 HP 8" grinder from before they put the model 74 on the tag. Type G ser#2199114, and I can't quite figure out what's wrong with it.
It turns well, it runs great once it's spinning...
