What will happen if I were to place a Model B distributor, or any other centrifugal advancing distributor atop a NuRex centrifugal advance unit?

You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command! -
Your advance timing light will tell. I would say timing would go out of site when the RPM is at a fast idle. In the short a lot of pinging. But that's just my guess. -
Maybe Bubba will knowComment

You'll have 19 degrees more advance than you should have, plus it will advance faster than it should because each unit will be giving advance.Comment

Good morning. I came across a Nu-Rex automatic timing advance . Does anyone have any experience or comments on using these? I printed off the instructions and they appear to be fairly straight forward. It states that there is ten degrees of advance for every thousand rpm, or thirty degrees at twenty eight hundred rpm. I was thinking of trying it on one of my engines, probably the B. How does...07-24-2020, 05:32 AM -
Ok, a bit of background first.
As some of you know I have been an advocate for the NuRex centrifugal advance and have been using one for 2 years without issue. Well, after reading the threads here about the advance and needs of the HC heads, I decided I would search for an alternate centrifugal advance distributor.
See, the stock engine with the 4.2:1 compression heads are...02-14-2019, 02:57 PM -
In the late 1970s, my friends and I used to hotrod V8 engines. We used to modify the distributor power curves by changing the weights and springs so that the mechanical advance would meet our specifications. We had access to a distributor machine at the trade school from which we all graduated from to confirm the modified power curve. I want to build a simple mechanical advance mechanism for a standard...06-09-2019, 06:11 AM -
Which way is best, Original with Nurex, Model B, Mallory, or electronic. And there seems to me more than one model of Nurex. Automatic advance is the goal.09-30-2017, 05:22 PM -

Now, I know this has been discussed in reference to the FSI distributors and high compression heads, but I need to get just a bit more info on the stock distributor.
I now have in my possession a Snyders 6:1 high compression head and I think since I can't afford a Mitchell OD it will be the next step in the ever changing "Touring Tudor" named Wheezer.
As...12-09-2018, 10:27 PM -
Gentlemen, as I compile the "wish list" for my new 29 Tudor, the Nurex system is one thing I am considering. I know the purists feel this is an affront to Henry's creation, but I'm not building a fine points winner. I plan to drive the car for a while to get the feel of the Model A as it was designed. I would like feedback from those of you that have first hand experience with the Nurex...09-27-2017, 12:16 PM -
For you real mechanics, what is the rattling, marbles sound that I am getting when climbing long steep hills? I am very reluctant to down shift to second because it is all over until rounding the crest and starting down. I know that I am lugging by keeping the car in 3rd for as long as possible and it rattles. But running at 30mph in second it sounds like a bunch of marbles. AER touring engine...05-27-2019, 02:57 PM -
Okay so there is always chatter about how great the Nurex Advance is. I drive my cars with the lever around 9:00 or a little less. I can climb hills, idle, and just about drive on all terrains by leaving it alone. Of course when starting the car it needs to be in the up position. I think most feel they have to continuously be moving the darn lever in order to drive the car. Why should I buy one?04-02-2018, 08:02 PM -
FSI offers the so-called 'Zipper" dizzy as well as the 'FSI' dizzy. The Zipper looks nearly identical to the stock A dizzy, but has a fixed advance total of 28°. The springs can be changed to alter the shape of the curve, but the total cannot be changed. It is most suited, IMO, for a stock motor with a 4.2 head. In actuality, if you are running a stock 4.2 head you will not have to change anything...10-26-2017, 09:42 AM -
