replacing pot in dme

[bell]

did my co2 adjust this weekend and noticed that the pot in my 85' carrera dme brain doesn't "indent" when turned to the next position, it does stop in position 1 though so i was able to adjust my mixture properly.
anyone have a part number for this indented potentiometer?
i like having the option to switch it for cheaper gas if the need ever occurs.

thanks

I searched my PET CD ROM catalog but they don't break the DME down to that level.

The fuel quality switch isn't a pot ... it is an eight-position octal [0-7] switch.

good info warren.
turns out that the switch works fine, where you insert the small screwdriver is all chewed up though which was hard to see with the dme mounted.....probably from the previous owner......or me....who really knows
i'm planning a steveW chip this spring so it'll be replaced at that time
thanks
