Fuel Cap for a 1931 Johnson OK55

[Adaily]

Hello,
I have been given an old Johnson OK55 1931 by a friend which is in very poor condition. There was not a fuel cap with said engine. Instead a cork was pushed into the threaded fuel fill hole. I have no idea what this cap looks like although there are several on line, but without a guide as to what they will fit. Is a part number available or a picture of what one looks like. The fuel tank itself is a mess, has several rust holes, dents, just terrible condition. I'm going to restore it but will still need that cap. Help if you can.

Thank you,
adaily

Thanks I'll do that. Here I am with 8 old engines and didn't know there was a club.

A machine shop could (literally) turn one out if you show them where it needs to fit. You could also use epoxy putty and a release agent and mold a "good enough" one.
