Gonna try to explain this best I can on the linkage near the carb theres a spring and a "nut" if you will, behind the spring (the thing that has the set screw in it) this particular thing has come loose, now my question is where should this be positioned once I tighten it up, once I replace cause it stripped[:@]? now this is right in front of the black arm on the carb arm.....thanks in advance hope its clear, BTW what the term for this particular pc?
