Hi all, i am attempting to adjust the carbs on an '86 Formula Plus. I have read thru the manual and other forums but cannot seem to get it corrected. The slides were a 1/4 to 3/8 inch from clearing the carb throat. Once i set the slides to clear the throat at full throttle they do not return far enough down to touch the idle adjustment screw. When the slides are far enough down to touch the screw they don't go all the way up. It idled correctly last winter so i know they are sitting way too high now. I pulled the engine to do some other repairs so i cant run it now, but i would like to get them close as possible before they go back on. Any suggestions?
