Hey I have a 78 f150 with a 351M. I noticed goin down the road the other day when I wud get on the throttle after about 2 seconds it wud start boggin down. Let off get on it and the same! Then today it started doin the same but at slower speeds and not hard into the throttle at all. Wud that be the carb goin bad?

 

plugged fuel filter would be my first thought.
