Great!, go buy a product called seafoam by OMC this goes in the fuel, it will clean out the carbs and help the rings, you may get lucky and not have to mess with the carbs, keep a eye on the waterpump as well, make sure its not getting hot!, with the cover off you should be able to hold your hand on the head, if it gets to hot shut here down just because its peeing water dont mean its getting water pumped up tight in all the places it should,

see ya, Bud.
