This has been a pretty good week for me. Picked up a Coleman 220E lantern, A Coleman 502 Stove ( my first) and My first European stove an Optimus 80. I think it’s around a ‘71. The girl I got it from said she bought for backpacking and only used it a few times. It was only a half hr drive to go pick it up so no shipping charges. I think I paid a fair price for it not too much but definitely not a bargain($50). Can’t wait to get a chance to try it. My question since I’m learning is what do I need to check on these stoves before I fire it up. How can I tell if the seals need to be replaced? What seal kit do I buy and how hard is it to take apart to replace the seals? The 502 cleaned right up just needed a cap gasket and fired up nicely. Just need to take the burner apart and clean the rings.The lantern well that’s going to be some work.
