Crosbyman,
From the looks of your picture, this looks like a 9r69. I have the same motor. It will drive you nuts. Look it up on LeRoy ‘s ramblings. The carb needs to be spotless. If you remove the low speed welch plug, you will find a plastic plug. This plug is shaped to direct fuel flow. It is not a part of the carb kit. I have found no references of this anywhere except LeRoy. Marineengine has a replacement for a few bucks. The plug is hard to remove. Be careful not to damage the metal. If you have a spare carb to practice on, that would be helpfull. I have cleaned the carb countless times. I will be lake testing it again today. If it is still coughing at idle, I am going to replace that plug.Good luck.
