I took my 4160 carb off the boat in late sept. to do a rebuild on it over the winter. The fuel was drained at that time. I took one fuel bowl cover to inspect inside, it looked extremely clean. I just took the other cover off yesterday and found white powder forming. I suspect that is is from moisture. At the lake I live on we have had lots of people complain about water in their gas.( People buy their gas from different locations, not just one place.) Put a good fuel water separator inline and stabil in the tank and forget it. I saw a video that showed a marine mechanic blowing air from a table fan over a glass of gasoline and it formed water droplets in a matter minutes. Gas is not what it used to be. Be sure to use stabil marine. 2c
