Any jug from any R or Z tractor will fit just fine. The jugs are all are part #RE(5)101A and the only differences are in the stroke and the piston compression height. Twin City and MM recycled parts forever. Later on, MM updated the part number to #10D1462 with no changes to the part.
Any TSX30 or TSX36 one inch carb would be correct for an EE engine. The TSX36 carb showed up after engine number 402201 rolled by, but the only real difference in the carbs is the standard Borg-Warner crap of changing one little part to cheapen something up. In this case, they changed the choke shaft very slightly.
