I bought a new house and the garbage disposal they left doesn't work.
It gets stuck on something inside the disposal. So I took the pipe and
top of to look inside and I found a thick (1/4 in) yellow rubber
lining that it's hitting and that is blocking part of the outlet. Is
that suppose to be there or am I looking at something old and
disturbing that should be removed?

Thank you for your help
