Nu Rex timing advance system

[Skeezixx]

I have my engine apart for painting and now would be a good time to install this part which I acquired in a box of parts but I can't find any reviews on it. Nor did it come with any instructions.

Has anyone tried it? Is it worth using considering the gyrations I'd have to go through later if I don't like it.

Snyder's part No. A-12176X

The instructions from Snyders is not the same as the part you show?

I have installed this in my fordor and am very happy with it. It truly is fool proof and as long as your timing is set correctly and the gyro can spin freely you will have no issues.

Just one thing though, when you drop in the new upper shaft, make sure it clears the hole in the head gasket, you don't want any rubbing or binding.

i used it for years and LOVED it...Setting it up is very important to get it to work really great.. You will love it. I now use a B Distrib which has it built in and just love that also.

Although the part number matches the Snyder's part number I think those instructions are for a different kind of gadget.

I have been using the Nu-Rex version for several years, and it works great. I've set mine up so TDC timing is with the spark advance 3 clicks down and with a little clamp on the grooved plate to prevent over advancing while allowing a bit of additional retard when pulling a hill, etc.

My only regret is the hassle if you ever need to remove the distributor, when the mechanism drops down into the valve chamber, the cover of which needs to be removed to reassemble. My oil filter increases the hassle. If I had to do it again, I would get an advance unit in the distributor.

I can deduce that it replaces the lower distributor shaft (I presume with the "gyroscope" in the up position. But whats with that spring part? Where does it go and what does it do?

[msmaron]

Does this help you out?

[Skeezixx]

I received a copy of the instructions from Nu Rex and Snyder's The spring replaces the original oil pump spring.

And thanks Mark, as they say, a picture is worth a thousand words.

Thanks guys.

How does that work?

B dist ?

Ok. I tried to install the part today but the shaft doesn't fit through the hole in my copper head gasket by maybe 1/32".

Looking for suggestions from our panel of experts.

drift punch ? I mean, all you need to do is ream it out.

Did the other shaft fit through?? and i agree, just use a drift punch...this should install very easy..Setting the timing of the car is crucial to this working perfectly.

We reviewed it awhile back, using a distributor test machine and found the results very good. Have not run it in an engine as of yet but the test machine showed smooth advance all the way up and down.

As you have found, the fit may be tight as it passes through the head gasket. Even if it appears to pass through, it can rub on the gasket and change the advance curve. Open the hole with a drift punch as suggested. A tight distributor bushing to shaft fit can also cause problems with the function.
How do I know this to be true? I just do! (Been there...it happened.)
Good Day!

I highly suggest you follow these instructions to the MINUTE...The NuRex device was formed from this unit. Phillips and if you set your nu rex to these exact specs you will be very very pleased

Good luck...mark

Apparently the NuRex unit does not come with the "Spark Lever Lock" as shown on the Phillips description on Vince's website as Mark shows above. At least my unit didn't include it. Would be neat if it did.

Correct it does not, i just used a black cable tie and it took care of it.
