Need information for tecumseh carb.

I have a Mtd snowblower with a Tecumseh hsk 600 1627t carb.I took pictures when I removed it but somehow I can't find them. Anyway when installing the unit to engine there is linkage to the governor and when installing left mounting screw there is a metal piece like linkage with hole that as I remember hooks onto the governor. From what I've read it is like the throttle lever. I believe it is a 2001 model. The lever I'm referring to seems to be bent from the factory for some reason.I have not seen another carb that resembles it with this lingage setup.I had a spring on it which I can't find.Any ideas about what this spring does or how I can purchase one.
