      What are the locations of the 10 A breaker and stop solenoid you refer to?

        They are specific to the motor. On the 4B the breaker is between the last valve cover and under the air sep (red button style breaker with a '10' on it mounted in a metal bracket).

        The stop solenoid is up on the fuel pump. If the bracket was a little loose the plunger wasn't drawing back in fully . . .
