    I found this 8r at a local Goodwill and was curious on its age. From what I have found on this forum, it appears that it’s from the late 50’s b/c of the embossed lid and tank color. Any more information would be appreciated. I loved it the moment I saw it.

    Thanks,
    Kristin

    Possibly 1959 but more likely early 60's. Impossible to tell for sure. Original paint, case in nice shape and nickel tank make that one a keeper. Great score! Wellcome to CCS, Jerry

    Thank you Jerry for your quick response. I almost hate to admit that I had no idea what this was when I saw it piled on a shelf at goodwill but have enjoyed learning about it. I will try to light it when a have the proper fuel. Thanks again for the response.

    Welcome. Nice stove. Compare the location of the heat shield on your stove to the one illustrated in Kerophile's post. There are detents on the ends of the tank that the heat shield lock into. You want that air gap so the tank stays cooler.

    I would recommend getting a new fuel cap gasket from The Fettle Box (see bottom of home page). I've found that leaking / hard fuel cap gaskets are the number one reason that these older gas pressure machines don't run after sitting for a long time. I have a few 8Rs and several Russian, Korean and Tiwanese clones. All work very well. A great design. Enjoy it.

    You will want to run it on pure Coleman Fuel. Automotive ''pump gas'' would burn, but the additives [for improved vehicle performance] are toxic and would also clog up the jet.

    Wow....thank you so much for the information. I’ve had a few people already contact me asking to purchase it. Someone offered me $100 but I just got it and not sure if I want to part with it. Thank you again for all your knowledge.

    @kerophile Do you have or know how I can get a PDF of the owners manual? I have looked online but cannot find one. I’m a little nervous to start it using a YouTube video.

    Hidden secrets of the Optimus 8R mini-pump cap revealed!

    The 8r is usually pretty easy to bring back to life. As stated above, you will want to replace the fuel cap gasket with one made of fuel resistant rubber (usually piton is that material). You also want do the same with the tiny rubber puck called the PIP. The link above shows this.
    Once dry these parts will not hold a seal. The parts can be had on the Fettlebox.

    Accessing the PIP requires a special tool but for your cap that tool can be made fairly easily. A flat head screw driver with a small slot cut down the center will allow it to mate with the screw.

    Have fun! Jerry
