I pulled all the bowls again, pulled all the screens from under the float valves and cleaned them again, checked all the slides, which were moving just fine.
I hooked the gas tank up to the carbs while they were out of the engine just to see if I could flood them. I let the fuel pump run for a good while and never saw any gas pouring from the carbs anywhere even when I opened the throttle. Im not sure If i would've been able to see gas spilling out after the bowls had filled up, so I flipped the carbs, one side over the other, and saw gas pouring out from both sides.
I know this is poor way of figuring this out, but it seemed as if all the bowls were filling up. Your thoughts?
