Thanx w8ye. I've seen your replies and have read alot of things you have responded to in this forum. You seem to be "fairly schooled "in the field. I really appreciate your help. I fired this thing up last night after soaking it for a while. It had never been run and was a little stiff so I let it saok in some warm to hot 10% for a few hours, cleaned it up and presto nice and free, smooth, and it runs great. I have another with a new sleeve piston rod and bearings just hasn't been assembled. Hence I wanted the specs for it. No doubt I can figure it out but having the book is a plus in my book. I'll never know it all. If I run up on something I'll just post my query here. Thanxs again. P.S. One day you'll have to explain that screen-name to me!
