Hi im new to this site and have a question.I just picked up a mule with what looks like a twin cyl kawasaki lawm mower engine in it.How do you find out what year it is?The guy said he didnt know what year it was but gave me a parts catalog for a kaf620.Well going on that i ordered a fwd/rev cable for it and the cable seems to be to long.If you could help me that would be great Thanks
