get a vac gauge and hook to the full vac port on the carb
adjust timming to the highest vac reading
adjust the 2 the idle mix screws to get the highest vac reading
reset idle speed,adjust idle screws again
check with timming light and note where its at
drive it,if it pings then back the timming off till it just pings a little on a hard WOT blast
check with time light see where its at with no pinging and make note..thats where it wants to run at
sounds like you might check the advanc curve in the dizzy to see whats up on it as well
Try what Mike the shadetree hickabilly rabid parts changer has suggested here... It should get you a better idea of where the engine wants to be timed.. Then put a light on it & see if any of your marks line up...... The deal on setting the timing at 34-36 degrees total timing is done with the engine running at around 3000 rpm so all the mechanical advance is brought in.... Setting it at 34 at idle would mean the advance curve has been locked out...

okay, i mark the crank 1" CW and 2 1/4" Cw from the factory mark at tdc #1 on compression stroke,
i cannot get the car to go to 35.5 degrees, i hooked up a vaccum gauge, i am only pulling about 14pds at idle, the car does not want to idle very good, when i put the car in gear it is so loppy it almost does not want to stay running in gear, i have to raise the idle 1000 to get the car to run okay and stay cranked when in gear, i cannot get the car to run like i want, new problem now, when i rev up the car, the rpms are steady on the tach till i get to around 2500 then the needle on the tach starts to wiggle up and down, and for some reason now, the car is turning off when idling, then a min. later running fine, i am totally confused now, why is the tach needle wiggling around when i put my foot on the gas and keep it at over 2500 rpms? the tach is a non-ralley and is brand new, just installed couple of mths ago and the car is not on the road, only cranking in my garage to keep the oil flowing.
I just reread this post about your tach.. Your running a Chrysler Electronic Distributor correct? Is the reluctor properly phased? The reluctor has two keyways so it can work with a smallblock or a big block.. If it is incorrectly installed the rotor will be past the proper plug wire connector with minimal timing & as you add advance it will induce what is known as spark scatter which basically means the wrong cylinders get fired & the engine shakes & studders.. The Tach may pick up the electrical signals getting wacky.. Just a theory..

Don,t get flustered the end result when that thing is rumbling will make your cheeks sore. O.K you set your timing fine at idle (leave it alone now)  You need to work on one thing at a time.  Total timing (34-36 degrees) is set when you rev the engine up to lets say for kicks to 2500 rpm hold it there and set the distributor to show (34-36 degrees) on the damper the way that was explained earlier in the post, once that is done then you recheck your timing at idle and see where it is as opposed to where it was initially, then adjust it by doing mods in the distributor. As far as the vaccuum advance it is only for fuel mileage, if you street drive alot then you may want it hooked up (I don't) for it to be hooked up proper it is NOT supposed to have vacuum at idle. Check the ports at the carb and find one that has has vaccuum only when you rev it up a bit then if you want hook it up. As for the fumes when idleing in your garage this is typical with a larger cam it is not efficient at idle due to overlap, but you can adjust the carb by using a vaccum guage adjust the mixture screws to get the most vaccum then readjust idle speed with the idle control screw on the side. Butt remember one thing at a time and don't get in a hurry.

with it a 1/4" before the 10* mark on the tab,it sounds close to where mine is at does it run and start good? the lower power valve may not be a good idea if its to low it can be open at idle and run fat IIRC you would want a stronger valve so it would open after the engine is reved up with a stock dizzy and a aftermarket cam,its not gonna hit on the correct #s as is from any FSM book...and they were very conservitive with it...they all run better alittle more advanced from the stock #s..usally around 10* or more with a 32-35 total,IIRC you need to recurve the dizzy and get the inital set and have the amount needed from the vac adv set(welding the slots) a stock dizzy will pull a lot of adv and keep pulling way past the point of to much need a vac gauge on the carb to set idle air mixture asap and recheck the PV for the rich condition setting by ear is never in the timeing marks on the tab from my experiance...allways just a little before the tab to the adv side take your time and one thing at a time like said remember...the damper could have spun a little and not be dead on any more and add to the confusion

okay, this is the strangest thing i have every seen, i have located the problem, however i do not know what it is, when i have the car running at idle, i grabbed the top radiator hose and squeezed together and the car dies, what the heck is this? i did this about 15times just to make sure, the strangest thing, is the car will smoke the back tires, however is fouling plugs and running way way to rich, and does not want to idle, what's up?

update, found one of the problems, the coil
was shorting out when getting hot, the reason the car was dying when i squeezed the hose, the water was being forced down on the water pump and pulling the motor down and coil was not putting out enough spark to keep the car running, so i have the problem solved, and not i can go back to the carb, i think my buddy and i have figured out somewhat, i think the jets are too big on the carb with the size cam that i have, so that is my next project

okay, i think i have found the problem, a bad dist., now my question is, what is the best set up for car, 73 440, 9/1 comp, 274 .494 cam, eddy performer air-gap, 750 holley vacuum sec., 727 stock converter, 3.55 gears, 68 coronet, i was thinking about going with the plug and play dist. from msd? actually going with the summitt brand, or do i just replace the dist with a rebuilt unit and hook up the blaster msd model 5900?

what about this dist. for my set up from 440 source?
-1002 Street Distributor - "RB" - Ready to Run - New
For more mild street applications, we also have our Ready to Run Street distributor. These feature a simple 2 wire hookup, and no external ignition box is required. A completely maintenance free magnetic pickup accurately triggers the ignition system. The increased output of the internal ignition system included in these far outperforms a stock ignition and will help to smooth out the engines idle, make starting easier, and provide a stable spark, even at higher engine RPM's. These also feature a performance advance curve setup at the factory, and a vacuum advance is included to help with fuel economy. Just like the PRO BILLET versions, these use "Spark Plug" style locking terminals on the cap to ensure a positive connection. Color of the cap may vary depending on stock. An excellent choice for street use. This distributor can also be used with a "female" (factory type) cap, see our part number 117-1011, listed separately.
