I'm sure it is the same guy, can't imagine too many people in Bremerton trying to sell SA-250s. If it is the same guy he must have panted this machine. It has been on Craigs list for about a year now. He will never get that price around here.
The SA 250's were good machines but not too popular here. The 3 cyl. Perkins is an outstanding engine but I've heard that SA 250's were known for vibrating way too much at idle and rad. supports and other things would get vibration cracks.
