Don't forget to make or install the bracket for that air filter housing if you're keeping it. My carb had a little bitty round filter on top, but the previous owner gave me the original unit. I have no idea how I got it home or drove it before I took the carb apart to rebuild it. In fact I couldn't rebuild it because it was so warped! After replacing the carb and installing the original filter housing again, I think I know how it happened because the bracket was missing and probably just bouncing around hanging off the side of the carb! I made one out of a piece of angle iron.
