macmic87, took your latest advice and reset the center carb 2-1/2 turns out, unhooked the vacuum and linkage to the outboards and started adjusting the outboards. I am now at just under 3/4 of a turn out with NO rpm change when I cover the outside hole and still pulling 20 inches of vacuum and the car idles great. Will test drive it tomorrow and get back to you. Between you and Bob you have really helped me out. If you ever need any carpenter advice just ask, been pounding nails for fortythree years.
