Winter project carb rebuilds

welp... mine is/was a Carquest kit, has different numbers.
I don't see a check ball on the drawing either. Backflow check is in fact a needle/pointed slug deal.
As for seat height, I couldn't finger out wtf was wrong, until I compared the pull offs with the new. Their books show it the be the correct kit for 4305S. Regardless, this one part was wrong.
