Right off the bat set your initial at 15 & get your best lowest idle speed & use the vac gauge method to get your ideal initial from there always bringing it back to your ballpark idle speed. With your initial finalized & that figure in hand shorten the slots to get 36 or 38. (this chart is from what they say fairly close). then toss the heavy spring w the long loop & sub in another one (not sure what's available) to go w the factory light one, mix & match staying just under the pinging point at WOT up thru the gears on your hottest/driest day then w the springs selected work in your vac adv striving for the fastest tip in again staying just under the pinging point using a 3/32" allen wrench(CW = sooner) (CCW =later as in more in hg vac to start the curve) at PART throttle (high vacuum) at an RPM above where the mech timing is maxed out at 36 or what you end up setting it at (36 would be a good start for open chambered 452's/todays gas). You want the most vac adv w it, and the mech maxed out. I'm going to try trimming the "tips" off of the advance weights (maybe 10% of its weight to start) in lieu of sourcing different springs to dial it (the springs) in that way & see how it goes.EDIT forgot the chart

edelbrock 750 carb (i know, i know... but its brand new and came with the motor ) or any other input? thanks!
Since it seemms that you have actually seen all trouble people have had with that particular carb you should do yourself a HUGE favor now and get rid of that POS carb. If it's new put it on ebarf and use the money to buy either a holley or a THUNDER series ebrock carb .

With Rapid Roberts timing suggestions, should be a nice streeter. Got a BG Mighty Demon 750 for sale at a great price if you are interested.

i guess i am over here in my own little corner of the world,i have had atleast 10 750 eddy carbs,and never had a single problem or complaint with them. run a fuel pressure regulator at 5 PSI,the front screws set at 2 turns out,straight out of the box,no mods,and thousands upon thousands of trouble free street/road miles and track passes.no loading up,no slobbering,no dead spots.the only trweaking i ever do to them,is loosen up the butterflys,slam the throttle arm shut a couple times,and tighten them back up. i generally do that with any new carb,just because they are all mass-produced. maybe it's just me...
consequently,with no more compression than you have,with those gears,that engine would be alot happier with a box-stock 600 holley. honestly,on that engine,a 750 is overkill.

half of them i have had,the people bought them brand new,put them on a vehicle,and start complaining about the problems. when i'm asked by those people what i think is wrong,my first question is "do you have a pressure regulator on it?" they say no,i don't need one. these guys will stand there,stomping their feet,arms crossed,like a little kid and swear to you that their 100,XXX mile mechanical fuel pump isn't pumping 5 psi,till they are blue in the face. so,when these goofballs shell out $300 for a new carb,and 2 weeks later want to sell it to me for $75.00 just to get rid of it,i snatch them up. then i can turn around,put it on someone elses vehicle,with a regulator,even a nearly identical engine,and show the original buyer how great it runs. they swear i have done something to it,it's not the regulator,blah,blah,blah. oh well,you know what they say,a fool and his money soon part ways....lol.

I'll check that on my 1406 as mileage is terrible (stock 318 in a 65 dart) and I haven't been able to find the cause

the chain parts stores (autozoo,o'reallys?,etc) sell a chromie MR.gasket inline regulator thats about $25.00. on a a nearly stock engine,i have ran them,in daily driving,set as low as 3 1/2 psi and worked great. on something your throttling on regularly,you can set it on that dart at 4 1/2 psi and be good to go. on the flip side,i have had guys put a regulator on their car,set at 4-5 psi,with a 600 holley,and the holley wasn't real happy with that.

I've seen those at O'reillys and I have one in my stash somewhere. If I'm not dripping am I OK? I sure wouldn't think a stock ('83 318) pump would be overpowering things but sumpin ain't kosher. (has a slight bog on easy takeoff) timing is 15 initial. 98's on the pri rods.EDIT meant 98 jets
