Re: Vacuum advance
OK, what I really want to know is whether the vacuum advance would cause pinging as described? At cruise rpm when on and off the gas ,stopping when given a bootfull??? Have I correctly diagnosed the problem? I have read the supplied instructions for removing the vacuum advance. The metal thread screw in the drawing has been substitued for a self tapper with a hideous socket head (torx or something) And there are no SHIMs in the kit, what are they are talking about?? My next step will be to email MSD.
