Te get a correct timing setting, the vac line to the dist has to be disconnected and the engine has to be idling slowly. It is very easy to get a false reading if the revs are up and the advance has started to kick in. 5 or 6 degrees retarded makes a huge difference on these flatheads in performance and temperature.
