Moonman, yes, it's set 6-82545. Smoke unit cam is ok and is the pushrod. The siderods are a little bent, just noticed that.
So, I just took all the wheels and drive rods off. Once off, the motor spun freely. When I put it back togethor, it works! Sluggish, but at least it's moving. I believe something has to be bent on one of the drive rods.
