It's me again. The new guy who needs help with just about everything that pertains to saws. I am new to this game. I cut a lot of wood with my dad when I was young. But just now got back into it when a friend of mine gave me a mac pro mac 10-10. Just running a saw brought back memories. Anyway's I need a parts diagram for this McCulloch pro mac 10-10. I was removing the chain brake to clean it and underneath it when a piece flew out and I didn't see where it went. I was outside so now I have a lost part that I am looking for and I don't even know what it looks like. I also need to know what the big spring orientation should be. A diagram would be so helpful. Anybody know where I can get it or the manual for this saw. I would appreciate any help that anybody can provide. Thanks. Scott Berry
