I have had the boat in storage for 9 months and it ran fine last year. I cranked it in the garage and seemed OK. In the water it was acted cold ran it a mile or so then went to idle and it cut off. Cranked but sometimes runs OK but then misses. want idle most of the time. I figured it was carbs so i pulled them and noticed a kink in the fuel line. I replaced it and put the carbs back on. It is doing the same thing as before. What should I do next? rebuild carbs? What is the most common problem? Thanks
