Only runs when starter button is held down is due an open dropping resistor or wire connection between ignition switch and coil input.
(An open is a broken path where there should be continuity, a short is a continuity path where there should not be one.)
My 706 diagram shows 2 wires off input coil post(+) One is bypass wire going back to starter solenoid, the other wire goes to the resistor and then through a couple of plugs and junctions back to ignition switch. Open connection could be anywhere in that path.
Resistor is used to drop voltage/current from 12 volt battery to operate 6 volt coil. Wire from start solenoid bypasses resistor when starter cranks the engine giving temporary 12 volts to the coil for hotter starting spark.
