I think my starter is going. When the engine gets hot it will do nothing. I got stuck at a show once. I turned the key and not even a click. Got a jump and started right away. Last night turned the key nothing, after doing the key 4 times it started. Do you think it is the starter solenoid? Also I started looking at starters I have a 71 350 with straight bolts. What is the difference in a starter that covers half the gear and one that does not?
