I have a 67 650 engine installed in a 69 royal star frame, engine ran great 40 years ago, Started it up again 4 weeks ago, with same points, same old points
plates adjustment, Idle was good
accerlataion was good,
I then disconnected the r/h coil to allow access to replace a scavenge oil line to the oil tank..
After doing this trying a restart It did not want to run at all over idle, Found a problem, I had some how reattached the positive leads to the negative on the R/H coi. l Not sure what damage this may have done to the points and coils/condensers
After I corrected this wiring I also replaced the the points plate with one which had better adjusters concentrics
Timed adjusted for inital timing, with 015 thou dwell gap, but still not /unsure in my mind to where to time the point is open or when useing on the AAU timimg marks scribed with a well defined scribed line on the cam or is it the square notch also machined on the same aau cam. The Scribed marks to me indicate to me max point open/dwell, of .015, So at what point on the aau cam are the points suppose to open
I can probably figure it out but what is confuseing , is that i have a square 1/4 notch on my timing cam as well as a scribed line on mine
