I have had problems with my 94 225 Venom idling. Sometimes it doesn alright, but most of the time I can be idling along and it will just die. There are time also when the engine will "sneeze" and die. I have read to check the syn n link on other posts. What is this talking about? I don't know what the syn n link is. I assume it has to do with the carbs being in sync with each other. How do you check this?
