I havn't checked the timing yet, but I suspect it's miles out. It's a zvh and has no vernier so I'm going to sort that when funds allow. Mine idles really high ie 1.7k and the brakes have no servo assistance so i'm thinking it may be down to vacuum/boost leakage where the inlet gasket was missing. I'm hoping it's all related. It's in my mates workshop atm so I will hopefully get time to work on it next week. Can you let me know how you get on with yours?
