1963 Merc 1000.
I finally ran some seafoam deep creep through my engine yesterday evening, letting it sit overnight. When I sprayed it into the carb throats (one at a time), it seemed to bog down the most on the bottom 2 carbs. When I sprayed the sea foam into the top carb, it didn't bog near as much as the other carbs.
If I hold something in front of a carb throat (I did it this morning), the engine will bog. It will do this for any of the 3 carbs, but slightly less for the top carb.
