Welcome to the Forum xwelder.
Sounds like you found the search bar, for the wealth of knowledge contain within these hallowed portals, and a bit more besides.
Sounds like you found a low milage Swing, any idea how long it's been laid up/ unused, as in, if the belts original it will certainly be in need of a new belt on age alone.
I see were almost neighbours, I'm in Bristol, should you need assistance.
My Swings in dry dock for the winter while I repair Tupperware damage caused by wannabe feral gangsta scumbags who tried to nick it, but couldn't hold it upright, and fell over with it.
Look forward to reading your posts
