My 253 blue with stock strom is running rough, timing is approx 4 degrees adv and at that its sounds ok( a little lumpy/no cam change just stock) but once into gear(Auto) it chugs and sputters. Been told its vaccum but with my little mech knowledge not sure what to look for or to do.
Any ideas guys, (in plain english please)
