When my 396 is cold and go to start it, I turn the ignition key and the engine turns over very slowing for about 2 seconds and then starts to turn over fast and then starts.
Once started and it warms up, if I shut if off and restart, the engine turns over fast and starts.
So, what causes it to turn over slowly when cold ?
My battery is new and I am using 10w40 oil if that matters. And have a high torque starter.
Can someone advise please.
