Hooking up a small gearmotor (electrical question)

Bought this vintage gearmotor at an estate sale.

It has four wires: two green wires and two black wires. I suspect that two of these wires need to be connected to a capacitor, either for startup or perhaps permanently (no idea on my part). Any thoughts on how to hook up this gearmotor?

thanks

See if you can talk to an old-timer at Bodine Electric -

It's a split phase motor, no capacitor. Connect a black and green together on each side of the line. To reverse, switch the greens to the opposite blacks.

Ned and Carmine, thanks. You are both on target. I just called Bodine and that's exactly what the lady told me -- tie black and blue (she insists they are blue) wires together in two pairs.

But you don't need a spool motor for an AC-TIG?! >8-/

There is a pdf file here for wiring diagrams that you might find helpful.

I recently found one just like it at the dump: Bodine, 2 green, 2 black. Mine was a *universal* motor (had brushes). I assumed one pair of wires was for the field and the other for the armature. Wouldn't a universal motor be wired like that?

Mine was a double worm gear, the first worm of which was stripped. That's why the "was's" (past tense).
