This was accurately id'd on the web site and fit perfectly.
But, as a non-professional, a schematic of the many gaskets and exactly how they fit would be helpful. This is because when I removed the two bolts that seemed to hold the old unit on, the carburetor, shield, and many gaskets all slipped down or off because the two bolts were holding everything together.
But of course, I am not a professional and move into these situations at my own peril. Thank you for the chance to vent.
