I don't know specifically other than ignition on. Are you using the solenoid for a HVAC step up? or to prevent a dieseling issue?

Yes I want to prevent "run on".
I can turn the idle speed down low enough so it dosent run on,but then it wont idle.
If I turn the idle speed up so it idles I get run on.
So I am looking for an ignition on power source to power the Holley solenoid that I have.

I agree MrSony.

I would go to fuse block and run a fused ignition on to the solenoid. But, perhaps I would rule out all causes of dieseling first.....
Mileage on engine?
What engine?
Modifications?
Fuel you are running?

Try this- do you have AC? Is there an AC fast idle solenoid on the carb? If not you can scrounge one up. If so you can wire it to your switched ignition circuit, then adjust it so that when energized it will keep the engine running at the right idle rpm, then when de-energized, it relaxes and allows the throttle to shut totally. The engine will stop. Don't use the pink wire- it is for the spark only. The cause is probably carbon build up in the combustion chambers that glows hot enough to ignite the idle mixture. It should be removed mechanically which means pulling the heads off, or chemically with an additive. In the old days we would slowly drip a glass of water into the carb at a fast idle and the steam would cleanse the combustion chamber. Don't over do it as too much water can cause hydro-static lock- meaning broken engine.
