Spout connector and Ignition timing

[mikiedreb]

I decided to remove and check my spout connectors the other day, both the one located below the cam position sender and the one below the coil pack. I ohmed and cleaned them both then replaced them. For $hits and giggles, I hooked up my timing light, started the engine, and noted the timing @ 10 BTDC. As I winged the throttle, the timing immediatedly ******** roughly 10 degrees then proceeded to advance off the marker as the revs rose.
I then removed the spout conenctor below the cam sender and noted the timing still at 10 BTDC, but as I winged the throttle, there was little or no retard, and a very small increase as the revs rose.
After re-installing that spout connector, I removed the one below the coil pack and noted the same 10 BTDC, however, as I winged the throttle, timing ******** then advanced as though it were still connected.
My questions are:
1) should the timing retard with the spout connectors in place as the throttle is winged?
2) do the 2 spout coonectors serve different purposes?

Sorry for being long winded....

Thanks

Only the plug at the CID sensor is a SPOUT (spark output) connector. The other is a common sensor ground and not associated with the base timing check procedure.
