I just purchased a super 77 not running, but its not tight.  The spec # is 17-1453, and Ser# is 14523-705. Can someone tell me what year this tractor is?? and production time frame?? Is it a 6 or 12v??, as the starter #107939 which i think is 6v?? The coil is 12v for sure. If it was converted, would the gauges be burnt out, as the tractor is not running??  Thanks Allan
