Im having some type of fuel problem. '04 90 mercury. I changed out my inline fuel filter today and it had nothing but broken pieces of fuel line in it from the ethonol. I took the carbs off but didnt take them apart. Went run it earlier and idled good and ran great until after i ran it. Slowed down and it killed. Tried to start it and nothign. It was flooded. I could smell the gas strong and could almost see it coming out the exhaust. let it rest and finally got it started. Got back on pad and could only run over 5000 rpms, under that and it wanted to shut off. got back to the launch and killed again. Tried to start it and once again, flooded. Any ideas???
