i have a 1989 48 special. it runs like a top starts up real easy and can troll all day without a sputter we rebuilt the carbs and put new plugs in it. it runs at 1`400 rpm,s when it is in neutral in the water. when i put it in gear it drops down to 1100.i have 3/4 17 prop on it .at top speed with 2 people it is going 30 mph on the gps.it runs like brand new but i can,t get the idle down. what should the idle be in gear at low speed?

Did you do the link and sync? When you reinstalled the carbs.

cleaning the carbs it's getting more gas, adjust the idle stop screw, that the linkage butts
