My 2006 DF 150 Suzuki engine is over flowing some fuel into my engine. I cleaned the vst tank and replaced the float needle and seat. I ran a clear tube from the vst tank overflow to a plastic bottle while running my boat today. When I got home there was about a 1/2 ounce of fuel in the plastic bottle. What could be causing the needle to still be passing? Maybe the float needs adjusting? Any help or ideas would be appreciated..
