13 ain't retarded unless the cam is pretty radical & this did happen all of a sudden I believe. Are we using ethanol (E10)?
Cam is pretty close to stock for a 71 build. This issue did just start this season (carb was changed over the winter). I think I am using E10, I believe that is all that is available around here.
I guess electric fuel pump is an option if I can't get any other way to work.
