Hesitation at 60 mph and up
Had the sock filter clogged just enough that it would run fine for 10 minutes or so then start running out of fuel , then let it sit and it would drive for 10 minutes again , had to baby a car home that way before.
Mine was on an old slant 6 diplomat that was just a to and from work beather so I just blew the sock off the fuel pickup with compressed air and drove that way for another year.
