Centrifugal Advance Has any one had much experience with the Nu Rex Centrifugal Advance Kit sold by Snyder's? I appears to be of high quality and looks great.
I just installed one and so far I am pleased with the performance. I am wondering about long term dependability as I have only driven 25 miles with it installed. Happy Thanksgiving |
Re: Centrifugal Advance Please let me know how you like it on some longer drives. I have one and we have been running some test on a Sun distributor test unit and the performances appears very good. I will be running an article in the next issue or so regarding the outcome of our tests and it would be nice to include your experiences as well. Please send any comments to [email protected]

Re: Centrifugal Advance i have an FS electronic self advance & really like it !

Re: Centrifugal Advance Is this the unit in the valve chamber?
|
Re: Centrifugal Advance I have had one and used on both cars. They are great. Really great and easy to install. But make sure you set the spark rod correctly to achieve the best results and just go to Nu Rex .com to but directly.

Re: Centrifugal Advance I am running a FS Zipper in my 30 Tudor and really love it. As mentioned above if you have questions or problems go directly to the manufacturer rather than the vendor.

Re: Centrifugal Advance I have been running a Nu-Rex in my Victoria for 5 years and about 6000 miles. Works great.
I thought I had a problem with it once, but discovered that when I had replaced the head gasket the shaft opening was not the right size and was causing the shaft to rub. The advance did not work right until I corrected the gasket opening. This allowed the shaft to turn freely. |
Re: Centrifugal Advance I am having second thoughts about this centrifugal advance unit. After checking the advance with a timing light, I observed that I get no more than 15 degrees of advance. Supposed to get 30 degrees. The shaft mechanism operates freely and I can move the distributor approx 35 degrees and the rotor falls very easily unassisted back to its original position.
I have contacted Nu-Rex to find out what their take is on this. I had High Hopes at first. The model A does ok around town but will not attain a speed of over fourty MPH highway speeds without advancing the column lever to compensate. So far the expense and labor (my labor) do not balance out. The old solid shaft driver operated advance operated much better in my opinion. I have very easily attained speeds of over 60 MPH in short bursts with the old manual advance mechanism. I guess I need to factor in entertainment though. Chet |
Re: Centrifugal Advance I just bought one of the NuRex units (from Snyders) and plan on installing it when my engine goes back together.

Look at post #7 by Donh: He is correct...when installing a new head gasket use a drift punch to enlarge the opening in the gasket the lower shaft passes through after installing and torquing the head. If you do not, it will rub on the shaft and limit the advance. Good Day! |
Re: Centrifugal Advance How does this work with a high compression head?

Re: Centrifugal Advance Quote:
My only gripe is that if you need to pull the distributor for some reason, the advance mechanism comes undone in the valve chamber, which then requires removing the side valve chamber cover, which, if you've got a full-flow oil filter, is more of a pain than you'd guess. If l had it to do over, I would go with the springs-in-distributor style setup. Steve |
Re: Centrifugal Advance Thought the high compression head required less advance? Do these units come for both regular head and HC head or can you adjust the max advance?
|
Re: Centrifugal Advance You're right about high compression needing less advance, but the unit does not come in two versions.
I set mine up with a timing light so it gives the maximum desired advance at high rpm; it's been a while since I fiddled with it, but I believe that this means ignition is retarded relative to TDC at very low rpm. ALSO, I've set mine up so I have some wiggle room (3 clicks of retard) allowing me to play the role of human vacuum brake on the advance, if I'm pulling a hill in an awkward rpm range for down shifting. Here's a photo of the little clamp I use to prevent accidental over-advance. http://i29.photobucket.com/albums/c2...vanceclamp.jpg Steve |
Re: Centrifugal Advance Growley Bear: regarding your post #9. I don't understand why after 80+ years of reliability everybody wants to re-invent the wheel?? I do agree with you in that when you figure in your labor, part cost, etc and then look at the result, it makes you wonder. JMO

Re: Centrifugal Advance That is exactly what I was thinking after I got it installed. If it ain't broke, don't fix it. I think that I will remove the modern in favor of the tried and true. I really don't want to reinvent the Model A.
The mechanical advance unit sounded like a good idea. I guess I was wrong. I'll wait for Nu-Rex to see what they say. Chet |

Re: Centrifugal Advance The endless debate over restoration vs. modification comes down to whether you see the car as an endpoint or a starting point. To my mind, a Model A, although not exactly broken, still just begs to be fixed. For example, when I'm driving around in town or running thru the gears, it just makes me feel good to think about the centrifugal advance doing its thing to make it run a bit better. The immense aftermarket-mods that immediately appeared for the A as well as the T tells me that my urges are "period correct." Or, maybe it's a genetic thing--I'm still not sure what all was done to my dad's Model A before it was even 9 years old.
