Hi Jeff
Turning the engine with the starter is ok for the tappets though it is more
important when doing the points to make sure the heel is right on the top of
the lobe. The rpm increase may well be from the timing change due to the
fitting of new or re-adjusted points, the bigger the gap the earlier they
start to open and vice versa.
