Hi Ed - nice find
The recommended tracking force for the MMC1 is 1.0 g but if it is worn you may need to "up" it a little. I personally wouldn't go above 1.5 g though as this is the point where you should really be looking to replace the cartridge.
HERE'S how to set the tracking correctly on a Beogram 1800 if you're unsure.

The use of metaphors should be avoided like the plague. They're like a red rag to a bull to me.
