Nu-Rex wrench ???

[wcmill]

Hey guys, was happy to receive my Nu-Rex timing wrench the other day…..not at all happy with it.
I’ve only owned my A for about a month, and am going through it from front to back as it had been sitting for 5 years.
I have read everything about these wrenches on this site. Still I can’t get a definitive answer as to why this doesn’t work.
This is what I sent Nu-Rex……..waiting for their reply:

Hello, I just purchased your timing wrench and am having a fairly big issue.
I have a 31 model A, it has the Nu -Rex upper plate with the modern Ford points.
When I set the wrench as instructed, I am no where near where the points are just starting to open. In fact the points are already fully open and riding right in the middle of the highest point on the cam.
If I set the timing the old way, with a test light etc, the car runs as it should but when I check it with the wrench it is at least 2 inches PAST the 4th point on the distributor head.
This baffles me, it’s just a simple notch in a cam with a fixed point matching to the wrench.
Some say it doesn’t work correctly using the modern points of non stock upper plate.
I find this hard to believe as the upper plate and points are also Nu-Rex!
Any advice or suggestions would be greatly appreciated.

Regards
