Near my house, there is a 25HP Superior located in an old grist mill that is actually water-powered but had the engine as backup power. This mill and it's surrounding the property are now part of a museum complex. My son and I now have permission to try and restore this engine which is a static display into a running display. This will be an interesting project and will entail considerable work. This engine was originally hot tube fired using natural gas from a well on site. This well was long ago sealed off and we would like to fire this with a Wico OC magneto and use propane. I have a magneto that I will donate to the museum but I don't have the bar with a roller that operates the magneto. I'm wondering if anyone on this site knows of one for sale or if none are for sale could someone give me detailed photos and dimensions so that I could fabricate one! Any help would be appreciated.
