I've installed the carb kit twice now over the past 10 years in my Johnson 65 HP carburetors. Today I took the boat out on the lake after it had sat up for about 3 years and the motor ran fairly well. (Last time I ran the motor I used a fuel treatment solution and of course, ran all of the gas out of carbs before parking the boat in storage) The problem I've had with the motor is it floods and dies when idling. Cleaning and replacing parts in the carbs from the kits have helped but I still have the flooding when idling/trolling problem. Here is my question. During the carb rebuild, there are about 4 plugs that I have not removed. I believe there are jets behind those plugs. Also, I may have not installed the little spring on the needle valve correctly and may not have made sure then float is adjusted correctly either. Could these issues contribute to the flooding while idling problem? I could sure use some advice. I will probably order the carb kit - 18-7222 soon and try once again to make sure I have the floats and the needle valves in correctly. Thanks for your help.
