    This cap was on a Johnson P35 tank that had been altered.As you can see the threads are gone on the cap.The threaded part was plastic as is the top.If I knew what it was from I could get one and run this engine until I can figure out something more appropriate.

    I don’t think the plastic cap actually came on
    motors when they were new but was a
    replacement. However aluminum caps that
    size can be found on Cub’s, Mate’s, and some
    4266 Pals at the end of the production of
    that model. 4207, 4253, and EARLY 4266
    Pal motors have a cap that is larger.
    I’ll get you pictures tomorrow of the cap
    I believe your looking for.

    You’re right Tubs,the cap definitely isn’t original.Some one welded a brass "reducer"into the tank opening.I’ve tried all the small Johnson caps I have and none fit.

    What I mean by replacement is after the war
    if you need a replacement cap for these tanks
    you would get this plastic (I think they are
    Bakelite) one instead of a metal one that
    would have come on the motor.

    Did some checking and I have a 1938 Johnson LS that has this
    same cap so maybe that is where the plastic ones come from.
    I don’t have many Johnsons but there must be others also.
    You should be able to find something. Sent you a PM.
