Today's parts haul;
As I have said before, mine would not crank using the key. Some of the reading I had done here, indicated a faulty ignition switch.
$25.00 at the local Kubota dealer.

Problem is, after installing it, the engine still would not crank using the key?
So I did some wire chasing with the volt ohm meter. That lead me to this relay;
A quick trip to the parts store, I installed the new one, viola! It cranks with the key.
Then I mounted this;
on the air cleaner bracket.
Ran some 8 gauge wire, just have to finish running the couple wires.
I went ahead and installed these;
Still need to deal with the high idle.
Pretty productive day. Won't be long and I'll be mowing with it.
I appreciate all of the help, you guys have been invaluable, in getting this far.
