casper50 Posted October 14, 2016 Report Share Posted October 14, 2016 Has anyone bought a vacuum advance from Andy Bernbaum? Just wondering if they are made in America or China. Took mine out to check it as I'm having lots of popping when running the engine and it has a tear in it. Quote Link to comment Share on other sites More sharing options...
desoto1939 Posted October 14, 2016 Report Share Posted October 14, 2016 (edited) Looked in my Autolite catalog under 50 Dodge Car. The first thing that you need to know is what distributor is used in your car because that determine which Vac Adv you need. Distributor Vac Adv Autolite igs-4207b-1 vc-3147 iat-4003 iat- 2023rg iat-4011 iat-2023rg I have a lisitng that I can scan for you send me you email. I would also look on Ebay you might find an Autolite NOS Rich Hartung Desoto1939@aol.com Edited October 14, 2016 by desoto1939 Quote Link to comment Share on other sites More sharing options...
Don Coatney Posted October 14, 2016 Report Share Posted October 14, 2016 This is one item where I would be leery of using New Old Stock. Using a 60 year old rubber diaphragm would not be my first choice. 4 Quote Link to comment Share on other sites More sharing options...

Dodgeb4ya Posted October 14, 2016 Report Share Posted October 14, 2016 That popping could have damaged your vacuum advance diaphragm if it's an on going issue. Quote Link to comment Share on other sites More sharing options...
casper50 Posted October 14, 2016 Author Report Share Posted October 14, 2016 It's been popping since I put the dual carbs on it. I found a large vacuum leak that I thought was the problem but once fixed it still did it so I checked the advance and found the tear.

Bingster Posted October 14, 2016 Report Share Posted October 14, 2016 Rich, would that vacuum advance be right for a 1947 Desoto as well? Quote Link to comment Share on other sites More sharing options...

suntennis Posted October 15, 2016 Report Share Posted October 15, 2016 Since Andy has a core charge, it would indicate he must get them rebuilt. Quote Link to comment Share on other sites More sharing options...

Seaside Pete Posted October 17, 2016 Report Share Posted October 17, 2016 Hi I have used a vacuum advance from AB on my P15 which worked perfectly, however if you look at his picture of the advance (which is not very good) what you see is what you get so will need to use some of you original distributor bits.

linus6948 Posted October 19, 2016 Report Share Posted October 19, 2016 (edited) I bought a rebuilt from AB this summer for my IGS dist. and it worked like a charm, keep in mind you reuse the internal spring and the shims (washers) from your old unit. Also you have to use a vacuum tester like a mity-vac to determine how many shims you need in your new rebuilt unit. My old unit had 4 shims in it, but I had to drop down to 1 shim to get it the new one to work properly. My only issue was tool marks/damage to the threaded end of the unit, looked like someone used vice-grip pliers to remove it, I had to spend some time dressing up the damaged end to get a good seal.

casper50 Posted October 19, 2016 Author Report Share Posted October 19, 2016 Thanks Linus. So you did not send in your spring and shims with your core? 1 Quote Link to comment Share on other sites More sharing options...
linus6948 Posted October 19, 2016 Report Share Posted October 19, 2016 I waited till the new one came and I was glad I did because all you get is what is shown in the close up, you get an empty unit, no spring or shims and no end fitting.

casper50 Posted October 19, 2016 Author Report Share Posted October 19, 2016 Tks will save me time as I'll just keep everything but the bare core. 1 Quote Link to comment Share on other sites More sharing options...
linus6948 Posted October 19, 2016 Report Share Posted October 19, 2016 (edited) Glad to help, apparently the IGS dist is a pretty rare bird and even the proper cap.rotor and points can be hard to find. I ordered a tune-up kit from AB and they work well but are cheaply made re-pops. The rotor and "two-piece" points look very chinese and the cap seems very light, I chose to not use their points as I still had some NOS points . But as I said the car runs well.

Linus: The points cap and rotor are very common items and can be found at most swap meets. I the point here is to know what caps, rotors and ppints and condensors cross reference over to the autolite numbers. This is why I have been collecting and scanning the various other manufacturers information and I have all of this on CD's. I even have a catalog that is a major cross ref to most of the common parts suppliers. Rich Hartung desoto1939@aol.com 1 Quote Link to comment Share on other sites More sharing options...
linus6948 Posted October 19, 2016 Report Share Posted October 19, 2016 (edited) Thanks Rich, I don`t get to many swap meets nowadays but I have had luck on ebay finding NOS components and I found the right cap on amazon and points from a forklift supplier HGM lift parts inc.. http://store.hgmforkliftparts.com/prestolite_forklift_parts/pligs-2224lb.aspx?afid=1&gclid=CjwKEAjwrvq9BRD5gLyrufTqg0YSJACcuF811HWqnqj52QCLXmcYh4V3sgQtwq_naoXOdRnaIlnKkhoC6G_w_wcB Edited October 19, 2016 by linus6948 Quote Link to comment Share on other sites More sharing options...

My old unit had 4 shims in it, but I had to drop down to 1 shim to get it the new one to work properly. When using the vacuum pump to determine the number of shims required how did you know only one shim was required? How many inches of mercury are required to start the advance and how many inches of mercury are required to be at full advance? Quote Link to comment Share on other sites More sharing options...
linus6948 Posted October 20, 2016 Report Share Posted October 20, 2016 (edited) I went with trial and error Don and my interpretation of the specs found on page 92 of the shop manual. Starting with the 4 shims and applying vacuum and getting no movement. I then kept reducing the number of shims until I finally got down to 1 shim and started to get movement at 7 1/2 lbs of vacuum and kept getting movement thru 16 lbs of applied vacuum. Now I don`t know if this was the correct way to do it or not, but I am more than pleased with the results and my car is running better than it ever has since I`ve owned the car. I`ve been using the heck out of it lately to take in the fall color which is peaking in the Mtns. right now Edited October 20, 2016 by linus6948 2 Quote Link to comment Share on other sites More sharing options...
