Jan, I can see a Zippo shortage developing in Denmark shortly!!!

Great fun! 

Just curious what Zippo/oil ratio you are using?  Everyone seems to have a favorite and they are all over the board.  I WAS using 5:1 Zippo to Marvel Mystery Oil.  Just cut back oil content, as it seemed a lot of oil was accumulating around the open piston end of cylinder.  Seems to run fine on 10:1 ratio of Zippo/Marvel Mystery Oil with less oil buildup which I assume is better for spark plug too.

Wish there was a bit of science behind these various mixtures !!!!
