Took boat out past weekend pump primer bulb crank motor notice fuel coming out were fuel line hooks up,remove cover and see leaking out lower carbs.boat hard to start and when it did ran at high rpm.took boat home and no further leaks out of carbs,think float may have stuck but now boat hard to start will run a few seconds and die.smokes alot now.I read that the oil injection can hang open.I removed plugs and 4 are carbon fouled and oily put 6 new in did same thing also got alot of oil soot on prop.I got the kit to remove the injection system but not installed yet.also heard maybe weak fuel pump.im leaning towards a over rich condition.was wondering if anyone else have had similar problems
