I'm not familiar with the Interspace, but if the pivot isn't designed to be lubed then don't. Do however, take the arm off the pivot and make sure both sides are very clean.
Try using a longish wood pencil or other non-conductor to lift and move the arm to the cueing position. It's possible your finger is bringing some electrical interference too close to the cartridge.
