Hello Bruce,
I appreciate your quick reply. I have spent a couple of days trying to track down these manuals via the internet and have had no luck so far...so perhaps this is my lucky day! There are 2 numbers stamped on this unit. The top number is 600021H. The bottom number is 11-052712 (I assume this is the serial #). This is my first time dealing with a McCulloch and I have a feeling it is going to be a real challenge. Looking forward to hearing back from you. Thanks again.
