A day or two ago I adjusted the clutch after 15000 miles because the gears where getting a bit clammey and difficult to change, thats what gave me the idea of 'clutch adjustment' unfortunately it has made no difference. I can only change down to 4th or 3rd when the car is already crawling along at about 20 or 25 miles an hour. I don't know if it is worth messing about with the clutch adjusting it either way. like I asked in a previous thread, 'does adjusting the clutch actually help for a smoother gear change?' I'm talking adjusting it in MM not inches.
Its an F16
