Same here, my assumption was 2 carbs=more fuel than single 4bl...plus mine is a 273 so overfueling seemed more than likely with 1405 and 6. Plus the exhaust would burn the everlovin' eyes right out of ya lol.
Agree, but when you are doing something new, you need a baseline with which to start. Can't observe, until you try something. Seems my intuition was wrong on baseline settings.
