Hello... I've got a 580C as well...I was running it home last winter and suddenly started to lose power... barely made it back like a lame duck...I checked fuel, new filters, return line clear, etc...I couldn't get it to rev up...just idle...anyways, I ended up removing pump which was a bit_h to get back stud nut off...
