I realise I may be moving a bit sideways from the original question regarding this mower but it is still the same machine I am having issues with.
I have fitted the new (second hand) 13HP B&S and wired it up.
I now do not have power to the starter solenoid with the ignition switch in the start position (no power in any position)
I have traced the wiring back into the look and it goes to an electronic circuit board up under the dash.
What does this actually do ?
Its part number is 25722433/0 though overseas the part number looks to be 125722433/0 (a 1 in front).
I could jumper this to get the power to the solenoid but this thing must do more than complicate my life.
In the mean time to sorting this, I will ensure all micro switches are not the issue but any input appreciated.
