I drove a '67 TR4a in college and drive one today...
This is actually from the Haynes Manual:
"It must be noted that to get the very best setting the final adjustment should be made on the road. The distributor can be moved about ¼ of a division (i.e 1*) at a time until the best setting is obtained. To obtain the best setting under running conditions first start the engine and allow to warm up to normal temperature and then accelerate in top gear from 30mph to 50 mph, listening for heavy pinking. If this occurs, the ignition needs to be retarded slightly until the faintest trace of pinking can be heard under these operating conditions.
Since the ignition advance adjustment enables the firing point to be related correctly in relation to the grade of fuel used, the fullest advantage of any change in fuel will only be attained by re-adjustment of the ignition settings"
"Method 2) Advance the timing to obtain the highest RPM at idle. Then, retard the timing just enough to reduce the idle by 100 RPM."
