Sorry if this is a daft question, but I can't get my head around it. I am fitting a brand new rocker shaft complete assembly to my 1964 BJ8. I have set valve clearances many times, but the tappet adjusting screws have always been close to the correct position. Not sure how to do it from scratch as one valve is set when the corresponding one is fully open, according to the rule of 13.
How do I know when a valve is fully open as the adjusting screws are nowhere near the correct setting? If I drop all the screws down to touching the pushrod cups, would this be the correct starting point?
Many thanks.
Graeme
