Does anyone have a diagram showing the vacuum port layout for a 2280? I found one model that has no idle adjusment screws-they're sealed. There are two small ports on each side of the front of the carb outboard of where the idle mixture screws would be, a larger one in the center front base (charcoal cannister?), and two large ones in the rear which I'm assuming is for a PCV and vacuum brake booster. Does it matter which one is used for the PCV hose? The choke pulloff is t'd from a port on the rear of the carb. Where does this other line go to? Is there a ported vacuum on the 2280? Thks. Mike
