Found my F40 book. Measure the #3. Adjust the throttle valve adjusting screws part #5 on both #1 & #2 carbs until they are within the specified variations. example, if #3 is 300 mm Hg then #2 should be 300-5 = 295 and #1 would be 300 -10 =290 mm Hg Hope this helps. If I find my F50 manual, I'll see if it says the same thing..
