    134? Should be in the FSM ... it is in the later TSMs.

    From the earliest manual I have (1972),

    Carter YF asks for 2.5 to 3.75 psi as I recall.

    The Carter 596S is the same. From the 1965 FSM.

    Thanks to all replies, very helpful. Changing to an alternator, high torque starter, and now electric fuel pressure..... guaranteeing a blown 2.2L engine soon. I AM just lucky like that!
