look at your output fitting coming out of the barrel valve, you should see a steel ball with a spring holding it against its seat. That is your idle check valve. they will work without it, but setting the idle is tricky.

the ron's combination valve doesn't have a idle bypass port the way a enderle K valve does. it uses a main pill with a idle check valve behind it.
