Hello, <br /><br /> I have Merc 9.9 HP,2002, 2 stroke. Has been running over 100 hrs. I have a hard time to start the moter most of the time at cold starting. Sometimes 3 hours later after first started and run. sometimes i found all the plug wet or foul.<br /><br />I just replaced impeller, Now It seems to be harder to start it. I wonder if these's something to do with Carb?. OR It is time to rebuild Carb?<br /><br />I have been cleaning carb with deep creep Seaform.<br />And blew it with compress air. I wonder that is not strong enough? Can I use auto carb cleaner (B120) for? I have been using boat regularly.<br /><br /> Any advice will be appreciated.<br /> Thank you.
