Vauum Advance w/ Carter YF

I removed the original dizzie from my Maverick and put in a C5 dizzie. It has one port for vacuum advance. When I connect a vacuum hose to the carb base, I get no advance. When I connect it to the exhaust manifold vacuum port, the timing goes way up and I get additional advance when engaging the throttle.

So, the question is, where do I connect the hose to? The stock setup utilized 2 hoses and that advance is no longer attached.
 
The exhaust manifold advance port?

a C5 dist would be a crap-o-matic IIRC... which means it needs a SCV signal.

I'm sure you meant to say "Intake Manifold!" :wink: What he means is you need a later dizzy with dual advance, such as came on the 67 and later sixes. :wink:
 
Yes, I meant intake manifold. I will install a Duraspark later but for right now I need to get it running until I find time to do the wiring.

So back to my question which is not answered, does the advance use the port from the carb or the manifold?

Note that the Duraspark advance I have only has one port whereas the original advance on the stock dizzie had 2.

it will take you more time to figure out the vacuum line than it will to hook up the wiring on the DS2.

DO IT!!! :wink: :D

Seriously. I do not understand what peoples big mental block is w/ the DSII swap. The first time your Load-O starts working anything less than 100%, the FIRST thing you should do is pull it out and put a DSII in. Even spending 30 seconds on trying to figure out how to troubleshoot the load-O is wasted time.

And this swap is SO FREAKING EASY. You take your old distributor out, and put the new one in - you plug in the module - and put 12v+ to the module.

Seriously folks... If you can change sparl plugs you can do this, and you will never look back. There is a reason you don't see 1/100th the "having problems w/ my duraspark" threads as you do load-o-matic threads...

There is reallly no excuse at all.
 
To answer your question. There is a "Ported Vacuum" port on the carb, which should have no vacuum at closed throttle, and increasing vacuum as you open the throttle. That port gets connected to the vacuum advance on the dizzy.

What was wrong with the dizzy you pulled out?
 
The vacuum advance was trashed and there was a nylon post broken which holds down the spring on the advance plate. I am just trying to get this beast running decent enough to get to the tranny shop and have some work done.
 
Trying to look at it pragmatically here, I can't see it working well enough for the trans shop to evaluate their own efforts.

It's a bit like blood transfusions; some swaps are less compatible than others. While you can "wing it" with an SCV carb and later distributor, the converse setup (which you're attempting) isn't really going to work well enough. Reason being, the vacuum comes in at the wrong (compared to expected) intensities during operation of the motor.

What I don't want to see happening, is bad trans work because the shop gets jack of a car that coughs and stumbles; they just throw their bits together with a careless attitude, ream you and forget about the job.

Can anyone loan you a points unit off a late '60s or early '70s car?

What is with the attitude???? Wake up on the wrong side or something??

That's Ian for you! One thing I really love about his posts is his attitude. I'd love to kick back with him for a day and just get rowdy with people. =) Take it for what it is, and his information is usually invaluable.
 
kukm, basically your distributor won't work with that carb. It's just plain incompatible. Get a later distributor from a parts store and just swap it in if you don't wanna deal with the wiring, or I'll PM you my phone number and walk you through the wiring of the DSII in about 15 minutes. =) Trust me, it'll be worth both of our time. Hell, you can even paypal me 5$ if your car is runnin' on a DSII in less than an hour. =)
 
Do the swap I messed with a carter rbs and load-o for a while and could never get the car to run right it always had a bad bog the duraspark corrected that. I even made my own wiring harness instead of using a junkyard one which made the swap take me about an hour.
 
To cut through all the B.S. thats going on and to simply answer your question :wink: The Carter YF needs a 1967 or later distro to run properly. The 1965 distro is only compatible with a 1100 Autolite 1 Bbl (or its equivalent) that has the spark control valve on it.

Running a Carter YF with a 65 distro means improper spark advance and poor drivability. :) It will run and idle but just not go down the road very well.

If your dist is a C5 part #, it uses neither, as I stated above.

Correct...

It's not attitude, it's the right information. If you keep asking me for a different answer when I have given you the right information 7 minutes after you posted, You might get a little attitude...

Just because it's not the answer you were hoping for, doesn't mean it's not the correct answer. Now, instead of having your answer in 1 reply 7 minutes after posting, you've wasted 7 other peoples time as well as bandwidth and taken 14 hours 32 minuets to arrive at the exact same answer.

Altho wasted is relative, because we are all just at work wasting our bosses time anyways.
 
Don, I have the original points dizzy from my 71 Mav ( 250 motor ) sitting in a box somewhere in the garage. Worked great before I put in the classic inlines DUI. You can have it if you want it. :wink: By the way, I have a YF carb on it.

Yes, because that is not a load-o-matic distributor, being from '71.

It's still not as good as a DSII, but it is worlds better than the load-o-matic
