Accucraft Quarry Hunslet - 1. Replacing the steam regulator valve
On this 7/8ths" scale loco, the steam regulator valve can be very stiff and difficult to adjust when hot. Jason Kovac, who runs "The Train Department" in the USA now supplies a replacement for all Accucraft locos), which not only overcomes the Hunslet stiffness, by using two O rings, but provides a much finer adjustment. In this short video I fit one to my loco and my apologies that my hands are not always right in shot!
