Koehler Generator Not Starting

I am having some issues with my generator not starting. I have 12 volts to the solenoid. I checked the pigtail where it plugs into the start switch and I have 12 volts on one wire. I can jump the solenoid and the engine turns over but will not start. Itís like I donít have power from the start switch to the solenoid? Any idea where this is fed from? Should I have power to either of the small wires on the solenoid? I cleaned all the terminals on the solenoid as well. This is a Koehler 7000w in a 86 345.
When this issue started I had just left camp and the generator died and wouldnít turn over after that.

I had similar starting issues with the Koehler generator in my 310. The issue ended up being the shutdown solenoid that stops the gas feed through the gas line. The solenoid is powered by the same wire that feeds the ignition coil. It's been a number of years so I don't remember all of the details but what happens is the shutdown solenoid starts to fail and as it fails it draws more current which in turn reduces the voltage at the ignition coil.

Here is a link to my post when I first started troubleshooting the shutdown solenoid problem.
