Hi, I'm new to outboards and my force 9.9 that I bought last year has allways given me problems on first start ups. Alot of times it won't start and flood out and still won't start after changing the plugs. I'm getting fuel and spark. I also noticed that it also seems to break up a little bit when running at full throttle. I'm using last years gas but I treated it for the winter. I have tried adjusting the carb using the way the manual says to do it. Nothing seems to be working. Any info would be greatly appreciated.<br /><br />Bob
