Well here it is, It's a 1974 according to the numbers. I got if off ebay as a parts machine. The motor and trans were both locked. I poured parts cleaner in both the motor and the transmission, even poured the cylinders full. let sit 2 days and it came loose in both the motor and trans. Over the weekend I worked on the starter, got it loose and now got the motor to finally run with some gas in the carb. will get more pics so you guys can see the next stuff. so far it runs and the machine is apart and pressure washed. I took the deck out new blades greased and all is working on the deck. Tested it under my 816S.
When found after sitting in a barn for 14 yrs in Charlotte, NC
