Centrifugal advance distributor
 

Wanting to ad centrifugal advance so wife can drive and not worry about manually adjusting. I have a Honda Civic points distributor I modified to fit.
Want to keep reverse polarity as original. Can I wire the armored cable to the terminal on the distributor and leave everything as is?
Thank You

Re: Centrifugal advance distributor
 

If mechanical points and not an electronic condensor, then yes. If electronic ignition then no.

It is not hard to change polarity. Since the battery is hidden under the floor boards, you will be the only one to know.

Re: Centrifugal advance distributor
 

I would guess if it is electronic it would also be 12 volt?

Re: Centrifugal advance distributor
 

Another thing to be concerned about is the advance curve. That will depend on whether you have a stock or higher compression head and other things. You don't want to have the timing too advanced or the engine will eat connecting rod bearings.

Re: Centrifugal advance distributor
 

It is a points dist. Are you suggesting I would need to reverse polarity? I was hoping to leave it pos ground to not affect charging.

Re: Centrifugal advance distributor
 

It's all stock. I will see what advance the distributor has and limit it. I think I read 29' is about the max?

Re: Centrifugal advance distributor
 

What year(s) would that be?

Re: Centrifugal advance distributor
 

You can use it pos ground no problem. The points dist doesn't care.

Re: Centrifugal advance distributor
 

In a nutshell, the Honda Civic points distributor’s advance curve full advance will come in at a much higher rpm. I don’t have exact numbers. For example max advance on the Honda engine will be in the neighborhood of ~ 4500 rpm. Whereas you want the Model A engine to be at full advance ~2000 rpm.

To accomplish this will need manipulation of the bob weight springs or the bob weights themselves. Also need a means to verify. Can be done in the car with a timing light setup. Ideal setup would be with the distributor mounted in a distributor machine.

Is it made to turn CCW. If not the advance won't work right. You will need to check total advance around 2k engine rpm.

Corley has done the Honda Civic distributor conversion a while ago and is considered the guru for this conversion. See link here:

I have a FS disributer in my A , its 12 volts negitve ground , ita also ,centrifugal advance , and electronic, it works good, and has given me no trouble

Re: Centrifugal advance distributor
 

Pan Head Guy, I was just suggesting that changing the polarity would be easy, IF NEEDED. Since it is mechanical points, positive ground is just fine. The only other polarity consideration is if the condensor is the electronic type, made using semiconductors. But I have never seen that on a car and it would probably not work because the ignition system rings, with positive and negative voltage on the condensor.

NKAMINAR, Thanks for chiming in with short concise info. Yup std. old shiny metal condenser, was more concerned with how the charging system reacts to reverse polarity.
Getting this heap read for the 4th of July parade. I did reach out to Corley but have not heard back from him.

Re: Centrifugal advance distributor
 

He favors the electronic Honda dist. which is happy at 12v.

Re: Centrifugal advance distributor
 

It does turn CCW

Re: Centrifugal advance distributor
 

I think '78....but some of the ones I saw in that era were different where they mounted, I picked one with points that looked right. Inthe past I have used CJ2A Willys Jeep distributors but on 12V and they are getting $

Re: Centrifugal advance distributor
 

It may be easier to get a Nu-Rex Auto Advancer. The advance is already setup for the Model A. Then you can use your original distributor and everything will look stock.

Re: Centrifugal advance distributor
 

I sure would like to hear from anyone that has the Nu-Rex setup in their engine and how does it perform? Lastly, how many miles have you driven with it installed? Is it worth buying?

Re: Centrifugal advance distributor
 

I do have one in my Town Sedan. Edit: I(t was) installed before I bought the car ~10 years ago. I have never had a issue with it. I set my timing for full advance at 28° BTDC. I have a high compression head.

Re: Centrifugal advance distributor
 

That'a a good trick.

Re: Centrifugal advance distributor
 

Sorry, it's early. "It was installed before I bought the car"!!

Re: Centrifugal advance distributor
 

Pan Head Guy, Just to let you know, the polarity of the generator can easily be changed by zapping the field coils. The field coils have a little bit of residual magnetism that snowballs when the car starts to become the polarity of the generator when it is changing. All the other electrical stuff, motors and lights, do not care with the exception of polarized LED's.

You have been very helpful. Thank you for your input!
