Anyone using the Nu-Rex tool or advance?

Not too many mentions of the auto advance gyro... I have one and it does the job...
My A has a B engine with some modifications... Stipe Cam, Brumfield head, downdraft carbs. When I had the standard B distributor with mechanical advance, the engine would run hot at higher speeds. After testing the water pump, radiator flow, adding washers to restrict the flow in the upper hose, all of that, I turned to timing. I looked at the timing with a light at all rpm's and notice that the timing mark only advance about 12 degrees max. I discussed this with Bob at Nurex, both in Hershey and on the phone and told him my story. He suggested that the original B distributor was not advancing the timing enough for my application and suggested the auto advance gyro. The car runs better than ever and the high temps at higher speeds is a thing of the past. I found it simple to understand and simple to install. I never looked back.....
