VPI Classic quirk

My 10 year old VPI Classic has performed without a hitch.
Change a belt now and then, a drop of oil for the motor and a dab of grease for the bearing.
Oh, and there was a spike replacement.

Every now and then, I can turn the motor on, it rotates counter clockwise. Turn it off, then its fine.
Any owners experience this?

I don’t want to bother with the VPI forum.

I have thought about giving Zep 4 a spin.
