Andy, That is correct, I am not running a vacuum advance distributor. Several years ago when I sent in my dist to FBO, I got it back with the VA plugged and I have always just left it that way because it was working. I thought that if I had any issues with it than I would change it back out for a VA unit. Now I have a better reason to reconsider that. Thank you for your reply.
