51 chevy w/59 235, 12 volt battery not sure about the starter.It cranks fine when cold.Even when it's below freezing. Once the engine reaches operating temperature however it cranks real hard. Brand new battery.Foot pedal crank. Sounds to me like my starter is hurting. Could this be anything but the starter? Timing? Just grasping at straws.Starters aren't cheap. thanks---Jack
