Default Re: Nu-rex Timing wrench

I too concur that it is a good tool to use to set everything as correct as necessary for a model A. As others have stated, once started, you will be changing the spark so it is a moot point as to perhaps 2-3 degrees off from the absolute recommendations for the set point. I have used one for several years now on my car and others and when checked afterwards was quite accurate.
