Well Champ ... I'm only trying to help the man out same as you are & could care less who is right or wrong ... as long as he gets his boat running right again. As for your statement about the crossflow carbs, I've had crossflow motors with mid & idle jets stopped up on 2 out of 3 carbs that did this exact same thing & a good carb service took care of the problem. It's all a gamble at best !
