I would recommend you reach out to our own "carbking", owner of the Carburetor Shop. I think if anyone may be able to help you out, it will be him. See the contact info in his web site for his phone number and contact days/times.
Let us know how things work out.

Out of curiosity I partially disassembled a 571S that someone gave me that is all crusty rusty. I was able to remove the part and it seems identical, at least on the outside. If you determine that it is the same part and can work in your 871 you can have it it for the cost of shipping. You can private message me if you want.
