clock dilemia

[lobie]

I've just fitted a genuine deluxe clock to my bus which is great but it gains 20mins over the course of 24 hours

does anyone have any idea why this is and can it be solved easily

Easy fix Marty. There's a screw on the rear plastic cover which adjusts the speed. Clockwise rotation will slow it down. 20 minutes is roughly half a turn. May need some fine tweaking.
