Hello! I’ve just gotten myself into stoves and am the proud owner of several now, some new and some old, and one I recently picked up is this Primus 8R. I’ve only performed a rough polish on the mechanicals and cleaned the box with simple green. After a few tanks of fuel, it provides a decent blue flame. I’m new to fettling so I’d rather not dig in on this one, since they appear to be rare. Anyway, finding this site has been an amazing resource for my new hobby. Thanks everyone!
