the motor squeals liker a banshee and works at 1/4 speed, dlv has looked at it and topped it up a little but it still doing it.. is there a clutch on it that might be playing up ? its now working about 20% of the time without squealing, i have to take my finger off and press again, and again, and again, the direction up or down makes no difference, nor gradient, time of day or temperature, or engine running.
