    Carbs need a good cleaning (removal). You could cross your fingers and add Seafoam to the tank but that's asking a lot of it.

    Also clean all plugs as they could be wet fouled due to the leaky carbs.

    yep sounds like a carb issue. look for cracked & broken hoses too.

    Leaking float valve needle. The rubber tips get a permanent groove in them and then won't seal. See if your oil smells like gas...
