Stepper motors on Rover V8 SU HIF44E carbs
Posted: Sun Dec 03, 2017 9:46 am
Im rebuilding some carbs for a Rover V8. They are the later ECU controlled carbs with stepper motors on the side. Unfortunately i stripped them down before reading in the workshop manual that under no circumstances should they be separated from the carb bodies. The manual states they are set at factory and shouldnt be disturbed.
My question is what will happen if i just bolt them back on? They are held to the carb body by three screws with no external adjustability, so it must be an internal setting of the stepper motor. However I assume they are just some kind of port or orifice opening and closing device and therefore their basic settings would be broadly similar and any further adjustments made by the mechanical settings of the carb?
Anyone done it before?
