I know this is the Lawnmower forum but, most people that use lawnmowers also use other items for yard maintenance as well.
Maybe a small engine mechanics forum with topics related to how we made something work, or what troubleshooting we've done, that kind of thing.
Just a thought... Back to the imbedded sawdust in a Stihl 048 and a recoil starter spring in a B&S 8hp motor..
