IMO you should check your timing with the vacuum advance unhooked and the timed port plugged. Then after you get your total set you can hook it back up. Sorry if I missed this and it was already mentioned.
No confusion on that. :thumbsup: I checked the timing with the vacuum advance unhooked and timed port plugged at various engine speeds to determine what my mechanical advance was. I then hooked up the vacuum advance and went through the same engine speeds to find out what my vacuum advance was.
