I just converted a SS 1980 35HP to long shaft. Since I virtually had to disassemble the entire engine to do this, I decided to paint it. It's all back together now and it looks and runs great. The problem is that I have one part left over. The part is 323107 and it is item 78 in the parts diagram for the exhaust housing. Unfortunately, the diagram is a little ambiguous as to exactly where this part goes. I'm having difficulty imagining exactly what this part would do anywhere near where it is shown in the diagram. Help please!
