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.

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.
