Re: Where should I start...Motor hesitant...
If gas can leak out of the fuel line, air can leak in and cause problems. Even though the motor gets gas, it may not get enough as you accelerate. As the motor tries to suck more gas, it may also suck more air resulting in a lack of gas.<br /><br />Try fixing the fuel line leak first to see if that solves your problem. <br /><br />A carb rebuild entails installing new gaskets, new float, new needle valve, new needle valve seat. While you've got it in pieces you should also clean it with some aerosol carb cleaner (espicially the jets). The parts for the rebuild can be purchased from any dealer in a kit. Really isn't a very difficult job if you take your time, have a manual handy and pay attention to how things come apart/go together. Do a search on "carbs" using the search tool above and you'll find lots of info on this topic.<br /><br />The lower unit oil lubricates the gears that transfer power to your prop. Should be replaced annually or if you suspect water has leaked into the lower unit.<br /><br />Hope that helps.<br /><br />Good luck!
