Hi...
Wonder if I might ask a question about engine timing?
An older Olds; still with an adjustable distributor.
Fender label says disable the computer, warm it up, and set the timing to 15 btdc.
Just watching it sit there, the timing "changes itself" by about 5 degrees randomly and almost constantly.
So would the distributor be rotated so that the recommend 15 is the most before it gets, or the average, or....?
Thanks to all who can offer advice.
Take care.
Ken
