BE CAREFUL HERE, PJ is right. Many of the new engines are being equipped with the newer inline starters. My IO-390 from Mattituck has one. These are equipped with a jumper that configures the starter for 12 or 24 volt operations. This jumper is easily confused with the jumper on earlier starters that connect the onboard solenoid to the input power terminal.
If you have one of these starters (they resemble two beer cans stacked together, or check with Mattituck), LEAVE THE JUMPER installed unless you are going to use a 24v electrical system (very rare on homebuilts).
The earlier advice on using the "I" (Ignition) is good if you have the other versions of the starter with an external solenoid.
