    Yes vaccum secondaries.
    I checked the #1 spark plug after my test run,and the very tip is kinda white now.
    I think I am gonna change them to about 65 each.
    Maybe they were both originally set at 46, if you run them to open evenly.
    With the progressive linkage, I am really running on the back primaries most of the time.
    What's the worst that can happen, I run to rich?
    Better then running lean, I guess.
    I am just learning as I go.
