Will DUI Distributor work with Autolite 1100 Vaporizer Carb

JMB

Well-known member
I still dont know if the DUI distributor will work with the Autolite 1100 Vaporizer carburetor. Any more info? Thanks
 
Can't answer about the vaporizer but......

The DUI(mechanical advance) on my bronco(170ci) seems to be working fine with an autolite 1100. I finally got everthing working Saturday and drove the truck around some. I haven't gotten the truck up to highway speed for very long as the tires are dry rotted(next project). I plugged the vacume port on the carb

No stumbles, flat spots or hesitation.

Carb is running a tad rich but I'm sure that's just an adjutment issue
 
Don't hook it up to the SCV valve on the 1100, hook it up to the manifold vacuum. If there is a ported vacuum source on the Ponycarb carb, you can start an argument about whether ported or manifold vacuum is better.

But everybody agrees that the SCV would not be a good thing.
 
NC-Fordguy,
Just wanted to know if you have any updates on your ford bronco with the DUI distributor and the 1100 carb. If you do , how does it run? Did it really give it more power? Were you able to notice better MPG? Etc...

Also , Who did you buy the DUI from? Was it easy to install? Thanks in advance.

I've taken it out on 4 trips to the next town over(about 40 mile round trip) since I put decent tires on it.

Truck is running fine after a little more fiddling with the carb.

Can't tell you if the DUI gives it more power or mpg as the truck was essentially non running when I bought it. It's getting about 14mpg now, but remember this is a 4000+ lb truck with absolutely no aero-dynamics to it. Flat winshield, flat grill, removable hard top that's a nice wind catch and a PTO winch sticking out up front along with 4.11 gears in the axles.

I got the DUI from Perfomance Distributers based in Tennessee. They answered questions and concerns professionally and demostrated they knew their products. The distrubuter was actually on sale when I bought it, not sure if still is. I'm sold on mechanical advance distributers as I have a MSD set-up in my 74 bronco with a 302. No vacume lines to fiddle with or to leak.

The install was easy to do. Get number one cylinder to TDC(I used a compression guage) and drop it right in. I did have to use a shorter bolt for the old distrubuter hold down clamp, but that was an easy find at the hardware store down the street.

The distibuter needs 12 volts to fire correctley. The old ignition wire was showing about 9 volts as there is a resister in the harness.(Common on fords with points system) I did not want to cut into 42 year old wiring so I added a painless auxillary fuse panel I had laying around to the switched side of the selenoid. This gave the needed 12 volts. This also put a fuse in the circuit, but I'm not sure if that's really needed.

If you get a dui from performance distributers it will come with instructions that are pretty thorough or feel free to contact me for any help you may need should you decide to purchase

IMO this was great upgrade over the old load-o-matic system
 
NC-Fordguy,
Thanks a lot for your reply. John @ Pony Carburetors told me that I should just get a Petronics igniter that goes in the distributor and eliminates the contact point. He said thats all I need and I will be better off. I dont know if thats true ( maybe he's right ) but if he is , it would be a much cheaper way to go. Do you know anything about this?
 
John always says to go with stock or near-stock. Don't worry, we know better.

Mike (AzCoupe) sells the DUI at http://www.classicinlines.com and all of the accessories. Either that or the DuraSpark distributor is a huge improvement over the stock Load-O-Matic even if you install a Pertronix in the Load-O.

Price for a DuraSpark II distributor and GM or Ford ignition module is close to what the Pertronix alone costs. The only minor issue is, you need to use manifold vac (or regular ported vac) rather than the SCV port on the 1100 carb. Not a problem in my book.
 
I had a pentronix set-up on my 74 a few years back and it failed just past the warranty and the worst time---in the middle of guardrail at tellico. Fortunately I was wheeling with another Bronco and did not have to suffer the humiliation of a jeep towing my broke down junk out.

I upgraded to a msd 6al off road ignition set-up and it has performed without incident. I've blown a locker, snapped an axle shaft, broke several u-joints and ripped out and exhaust sytem and the msd has never failed with all of the abuse I put my 74 Bronco thru.

I talked to someone at pony carbs about my 1100 when I was trying to figure out what to do. I wasn't impressed with the answers nor the price for one of their carbs. This coupled with some of the flaming on the Bronco Board by other members about carbs(autolite 2-V) from them.
The guy on the phone said something akin to we correct the factory flat spots, hesitation and stumbles. In my 25 plus years of wrenching I've never seen a carb that did not have these issues right out of the box. You gotta tune them to match your engine, altitude and the type of gas your running(ethanal sux)

X2 on the post from wallaka. IMO either the dui or the duraspark is a better way to go. I opted for the DUI because it eliminated the need for a vacume advance and instalation was a breeze. One wire hook-up is about as simple as it gets.


Hopefully this doesn't double post again :?:
 
Thanks for the info guys. Clifford Performance told me to go for the Mallory 4763001 Unilite Breakerless Electronic Distributor Vacuum that I can buy at amazon.com for $ 335.40. They said it is better than any other distributor for the 200 inline 6. Do you guys know anything about this?
 
Not as good as the DUI in what way? Cuz I specifically mentioned the DUI distributor to them and they still insisted on the Mallory Unilite. In ranking order , what would it be if you were to rank the distributors BEST to WORST for a totally stock 200 inline 6.
 
Well, they would tell you that the Mallory is better than the DUI for a 6 because Mike at the Ford Six Shop [linked below] - that is to say, the sponsor of this website/chat room - is the only one to sell the DUI. Mike also helped DUI develop and test it. Clifford sells the Mallory. 'Nuff said?

Oh yes. He is also currently working with Pony Carbs on all things six-y and sells the Vaporizer through his shop.
 
I have no PERSONAL experience with the Unilite made for the 200. I had one on a 302, however, and the optical sensor was flaky. And expensive. Don't know how common the problem was. It was a good distributor except for that. Better than a stock DuraSpark? Not really.

The DUI is custom curved for the 200 already, uses off-the-shelf parts, and you don't have to buy a separate coil. Plus it is about the same price. Clifford will say their product is the best--they would be stupid not to.
 
Hello fellow bronco owner, my 2 cents is that if you have a good stock past 68 dizzy with pertronics, use it, I am about to install a blown 200 with pertronics 2 and 60,000 volt coil from pertronics with premium brass tterminal cap and autolite racing plugs 33's. If you have the money buy the DUI from Mike, for its top of the line, otherwise for stock its not much of a gain IMHO.

That's about what I paid for the DUI
 
A personal note on clifford from my experiences since using them from the mid eighties and have spoken with Jack several times, since Jack died in 2001 clifford has been headed downhill ever since and they aren't 20% of what they used to be, I also know the new al head Mike has drives Larry crazy and he is always bad mouthing Mike which really bothers me.
 
The reason Mike's aluminum head drives Clifford crazy is because they promised they were developing one for about 10 years and never delivered. Instead they now offer a "blueprinted" log head for $1,095 and there is no mention of an aluminum head.
 
When I think of parts/info sources for Ford Sixes, Clifford isn't even on the radar. They once may have been THE source of parts, but not any more. And their know-it-all we're-the-best attitude has completely turned me off.

And the Mallory Unilite? Hah. Don't waste your time/money.
 
I know this is an old thread but I am getting ready to install a New 1100 Vaporizer and a New DUI distributor from Classic Inlines.

My question is:
1) Where do I connect the vacuum hose?

I know I have to connect it to the Intake Manifold Vacuum port but I dont know where is it located.
Some say I need to get vacuum for the dizzy from the base of the carb not the intake itself. While othes say it is on the Intake Manifold.

2) Does anybody have some pictures to that show where these Vacuum Ports are located?

3) Does anybody know what fitting do I need to install into the Manifold Vacuum Port and where to buy it?

4) Do I need to put some kind of teflon tape on the thread of the fitting or not? Thanks in advance.
