theyre in the baseplates and I'd use a jewelers screwdriver to adjust them- not a flattened coathanger. and they break easy!

OK HERE'S THE LATEST. SET ALL SETTINGS ON ALL 3 CARBS AND ALSO CHECKED FOR VACUMN LEAKS AND THERE WERE NONE. CAR SEEMS TO IDLE DECENT BUT THE ONLY PROBLEM IS THAT WHEN IDLING AT SAY 850 RPM'S THEN WHEN I REV IT THE THING MIGHT SAY IDLING AT 1100 RPM'S. I CHECKED TO MAKE SURE THE OUTBOARDS ARE CLOSED AND ALL THE LINKAGE IS WORKING FINE AND THERE IS NOTHING HANGING UP PLUS HAVE A STRONG RETURN SPRING. COULD THIS BE A TIMING ADVANCE PROBEM IN THE DIST. AND THATS WAY IT DROPS SO MANY RPM'S WHEN I PULL IT IN GEAR AND THE RPM VARIATION ?
thanks

That is caused by your advance springs in the distributor.
Get one lighter spring and put it in....that may let the advance stay up higher even at a low 800-900 rpm.
I had to fiddle around with the springs because of the same high 13-1400 occasional idle. Using 2 real light advance springs keeps my timing well advanced at 30* or higher from 800 rpm up, with full 35* coming in at 1500 rpm.
Runs real nice even with the haywire XE295HL cam.

You need the springs to be stout enough to keep the weights retracted at your idle rpm. Here's a chart that may help.

I suppose that would work too....just that you'd then have a real slow advance 'cause of the spring tensions. My problem was that with the raspy XE295 cam, I needed the high initial (18*) and very quick curve in order for the engine to not stumble. Beleive me...me and my son spent HOURS.....or should I say DAYS....setting up the advance to get that SOB to idle. It DOES NOT do it's "sometimes high idle" thing anymore, and it will idle at 800 rpm quite nicely (well...NICELY for that nutso of a cam).  If you have any kind of lumpy cam in there, I would tend to think you would have to go looser like I did. All this info was originally fed to me thru guys here on the forum. I did what they said...and it worked. What else can I say??

HOW HARD IS IT TO CHANGE THE SPRING
To change the springs you have to take the screws out on the side of the distributor, gently pry the reluctor off the shaft and pull the plate out.
Mark the reluctor in relation to the shaft first with some paint or a pen. We had to do a bunch of welding on the slots to close them up for "superwrench". His car was WAY better after just welding the slots a bunch but it works kind of like a locked distributor curve with a built in spark retard for starting. Light spring that gives just enough tension to pull the weights back below 600-800 rpm. His car idles around 900 -1000 when racing so it works great for him and super responsive.
I'm not really sold on it being a timing thing though for you, unless you have the vac advance hooked up and it's on the wrong nipple.
Did I miss it or did you say what Cam was in your car and how much vacuum it makes? Usually what you describe is from too much of the advance port slot showing under the throttle blades and when the idle goes up it makes the advance come up and creates a higher idle again.
Got to go make my kid some supper, I'll check back later to see how it's going for you.
Don.

I had the exact same problem that you are describing in your first post. I followed all the tips that people have posted here and was able to get the car to run absolutely great with the exception that when I dropped it in gear the idle drop was several hundred rpm and the car was very unstable until I was rolling.
Larry Shepard came out with a new book on tuning and working on Mopar six pack motors. I got the book and it contained the best advise I have ever received. He said that for automatics you should richen the outboard carb adjusting screws almost one whole turn. I did it about a half a turn (from the 3/4 they were at) and it made a HUGE difference. I had to lean my center carb a bit, but now it idles in park or drive at about 800 rpm with very little difference between in gear or not. Still runs very well. A little rich, I need to tweak it a bit, but a very large difference. Drives great now!
Mine is a 440, stock motor and cam, Mopar dist set at 38 at full advance. Jets at 64 in the center carb

I should clarify that 800 rpm idle....that is IN gear....the engine actually free idles at around 1200 rpm...but it DOES NOT try to flare up over that, and I don't have to blirp the throttle to get it to idle at 1200 rpm...it goes there the instant i take it out of gear. Of course I have a real loose convertor too, so there is no way that you can even feel the car drop into gear. You'll get it somehow....all I'm saying is it could be a long drawn out affair...but when it works...you'll be gratified!!! Perseverance is the key.
