It's an Edelbrock 650 cfm with an electric choke.The manifold is Edelbrock, too.
I have a vacuum gauge at hand, but cannot get the car out of the garage, because we have snow at the moment.
Do you think, it can be a carb issue? Why should it start when jump starting it then?
Oh, I forgot to mention: When hot or warm and trying to start, the engine turns very slowly like having not enough power to turn it. When jumpstarting, it behaves like normal.
Maybe there are 2 problems. Can it be, that heat lowers the electrical power to the starter and the ignition?
