Deb,
Not sure if the hidden filter is shown in the manual.
Follow the fuel line down from the petcock to where it connects to a T between the carbs. Pull line off of T.
Hidden filter is inside here.
Page 9.6 of my manual shows the hose in top part of the picture but filter not shown. It will be in the bottom end of this hose.
