The plug is the TDC lock. 1 side is short and the long side is slotted. Turn the engine over and at some point you will see a blade near the TDC point. Find TDC on the timing pin under the pump that goes in the cam gear. From TDC on the engine, then turn it over to get TDC on the pump. Put in the slotted side and screw on the nut to hold it in. Loosen the pump gear nut and pop the gear loose from the shaft. Turn the engine back to TDC. Snug the gear nut. Remove the pump TDC pin, then torque the gear nut.
You should be at stock timing.
Yeah I lined the pin up and had the engine at tdc but I wonder about it. Does that blade always set it back to stock timing or does it matter if the pump has been advanced before? I read somewhere that if you advance timing from say 14* to 18* then pin time it the pump will then be 18* whenever you pin time it again. Is that true?
