Okay, I haven't managed to gas up my Ego to find out its an actual problem yet, but my back block ha on the solenoid has a slight nick on one side and a slight dent on the other. (doesn't appear to have pierced through)I'm hoping it isn't bad enough to have effected the marker. But I preparing for the worst and so have started to look for stock. A few places have it as listed but out of stock. As its an old part I'm assuming they won't get more, so anyone know of a shop here or overseas that still has stock or anyone who might have one in their kitbag.
