I have an Economy Jim Dandy, I think it’s mid to late sixties? It’s been in my basement for almost thirty years! Every now and then I dump a little Marvel Mystery Oil in the spark plug hole and spin it over a few times. I probably should sell it because at this point I’ll probably never use it! I bought it in 1984, when I was 14 and I’m the third owner, also still have the mower deck for it!
