Thanks for reporting back, Rob. The error lies predominantly with Tecumseh - it is not normal engineering design process to have parts that can just as easily be installed backwards, but cause problems if that happens. There should be, and normally is, either an assymetrical mounting so it would only go on one way, or the word "Top" pressed into the component to show which way it goes.
I will close this thread - if any member has something to add to it, please PM a moderator.
