Could to many turns anticlockwise (out) be the cause do you think?
Will cerlook at cleaning the carb out as you suggest if it isn't jus a miss understanding of terms on my part.
Idle screw is nothing more than the "fine throttle" at the closed position of the carb's butterfly. You screw the adjustment in - you're opening the throttle, means motor starts to run faster, and vise versa.
There is no "set" position for this idle screw. Play with it until the needed speed of the motor at idle "starts licking" your ear.
I've always cleaned my carbs with gasoline, disel fuel or kerosene.
Try doing something tonight and then post results.
