I am just wondering, is there a way for me to tell if the engine is running rich? The engine is a 94 Mercruiser 305, it was upgraded over the winter to an Edelbrock Performer RPM Airgap Intake and a Edelrock 1409 Carb. It seems there is quite a bit of black soot building up in the Thru Hull Exhaust. This has only been from idling also. No higher, as I have been using it on the hose so far, will be lake testing in a few days.
Just wondering if this is a sign of it running to rich. I pulled the plugs the other day and they seemed ok.
