I am not pointing fingers at anyone specifically but sadly as I have followed this thread, I have come to the realization the real underlying problem with our hobby is
US. To many hobbyists, because they seemingly have the inability to "problem solve" as a mechanic, they look to a 'tool' as a cure-all to make up for their inadequacies. In addition to that, hobbyists resist taking time to study the original manual and Service Bulletins ...in essence choosing not to read the
real instructions first.
Look above at
all the people who have stated they do not see a need for this and compare it to their track-record of advice they have given here over time. Also, think about the Will's, the Marco's, et/al and determine if they see "the need" in using this for their engines. I think you already know the answer! If I am reading what has been posted above correctly, folks are trying to use this "problem solving" tool as a means to correct excessive Drive Gear backlash, worn or improperly made Dist. Cams, worn Distributor bushings, aftermarket Distributor Bodies, and so on. If the distributor cam lobes are worn where the ignition points do not open at exact 90 degree intervals, --or if the dist plate is loose within the body, this tool will not cure those issues. The same applies to the "backlash" many engines experience. Please take the time to fix the underlying problem(s) FIRST and see if you don't get a performance gain without using this tool!! Please don't try to convince us who have taken the time to study how a component works, and then made the effort to bring everything within proper tollerances & specifications that a tool such as this is a 'must have' for our tool box. If it had been, ...wouldn't KR Wilson have manufactured one many years ago for Ford mechanics to use?
Now on the other hand, if we were talking about swapping to an alternator .........
