Hello, Does anyone know of an online repair manual or diagram of a yanmar YSB 8Hp. I am having a throttle problem, I can start her up and she will rev up like a run away train, without even touching the throttle. it's really odd she sounded fine one day then I started her up and she started surging, and now like I said she just runs full bore. I actually have to go below and physically push the arm attached to the injector pump. Any thoughts would be great and as usual, Thanks
