Actually if you need a carburetor assy. any from 1986 to 1996 will work as assemblies. Include part numbers that supercede:
397712 to 432168 to 434622 to 436718 to 439393. That was just a quick look. Those motors stayed relatively unchanged for all years of production. As long as the carb is used as an assembly you won't run into any minor jet changes.
