New stainless steel.  We have these made new. If your springs are weak- linkage will not snap back. Your spring may look fine, but if your linkage doesn't want to close, your spring is probably weak. I find this problem often in our rebuilds.

S-9571-SS

I have produced my own carburetor.  VS-9T7.  Check my E-Bay listing # 363898763577.   Listing shows chrome finish but available in standard finish.  Available as primary or secondary application.  I have worked out all of the “kinks” that other reproductions have encountered.  Superior quality and workmanship.
