Howdy...I have a 1953 series 6400. Not sure what the engine is. I found a # on the passenger side right in front of the starter,"00774I9 F54ZC". When I took the starter off, there is another number,"CON L53". On the head, theres a number,
B13 887
066
570
I tried to look up all the numbers on the inliners website and came up with nothing. Am I looking at the right numbers? Also, is there a difference between the engine serial number and the casting number? I didn't find any kind of plate on the drivers side of the engine to indicate a babbot engine, and theres no shroud at all around the sparkplugs. Boy...Do I feel silly, I can't believe I can't figure this out!
Assistance please!
