okay so i've been away for a while, at first everyhting was on the up and up... But lately i've been licking the wounds of this hurting chrysler.... the throttle plate had craked on my carb and was causing enough problems to foul 3 plugs and tommorow, im getting new ones... Then it will be off to grease monkey for a rear end servicing...
And hopefully all my "little issues" will be gone by the time of the Raceway park swap meet at the end of the month...
Moparkidd being the swell fella he is, has givin me (for a steal) his 600 cfm, electric choke 4 brl holley... its on it seems to do everything ok, but i do note that the lincage isnt the same as it was on my stock one. and its taken some fenagling to make it work...
So to the point... i have 2 issues
1. it seems the pedal doesnt completely go home after you let off the gas, as in the throttle doesnt return to idle, its sticks just a tad little open? any ideas? i wd40'd it and that seemed to help... but i still wonder...
2. this ones a big issue... before when id get into the pedal you would get that kick down as the secondaries opened up... the sudden power surge.... now she just sorta continues into the acceleration (like there no passing power on the highway)... is this something that has to be adjusted or am i missing something obvious...
Some one give me a long explanation.... THANKS and its good to be back... I hope.

Dana. ..John's not too good at explaining himself.
My drift of all of it the kickdown isn't working. I have to think the linkage adaptor may be part of the cause. He said he had to manipulate the throttle. Maybe it's not opening all the way, or the rod isn't connected right.
I guess I need to invite his can up here in a couple of weeks again . . . .

Well, if he has something up with the kick down, ie just be careful not to adjust it so far out as to limit the carb from opening all the way...been there done that

sighs....
1. the carb doesnt close all the way, remains at partial throtttle... put on a heavier return spring (the one that pulls carb shut) but still sticking...
2. im pretty sure the carb's opening all the way, it just doesnt kick down at the appropriate time.... like when your on the highway and you want to pass, however seems to give a small kick down in the 25/35mph zone... its very odd
i had three plugs fouled just as i thought.... foulded in this case equaled smashed down, apparently when the throttle plate cracked a small piece went down the intake and whacked the plugs leaving no gap at all... so the 440 ran on 5 for a week... HELL of a motor...
I shoulda put them in on my own... It cost a c-note, and found out i need front brakes and motor mounts, the heat guard on the steering colum is hitting the manifolds AGAIN too!
If you get some free time steve please ask your buddy at the part store for price on those mounts... im hearing over 50 a set, two sets needed...
What a shame...
thanks guys, and ill try to be a little better with my descriptions...

John,
I'm going to weigh in on this because I restore carburetors for a living. I can't advise you upon what exactly to do for your Holley because I refuse to work on them anymore. They were designed by a sadist in a drug-induced stupor and are good only as wheel chocks.
I am going to offer some advice, but first we must first determine what carb your Holley replaced. If it was another Holley you can probably use a Carter AVS with very little adaptation. If it was a Carter Thermoquad, you are stuck with a Thermoquad (unless you change the manifold or use an adapter) BUT I would take a T-Quad over a Holley any day.
I have performed a Holleyectomy upon our '70 and '71 and replaced them with AVS carbs; they never give a minute's problem. Of course, I restored the AVSs but I never could get the OEM Holleys to work right no matter how much work I performed upon them -- and the "aftermarket" Holleys are worse! I can restore an AVS or T-Quad for you, but the cost and turn-around time would probably be prohibitive. Perhaps someone on this site who has had luck repairing Carters can help you more economically than I can.
I'm sure that the man who sold you the Holley was just trying to help but, whatever you do, get it off of the manifold before it sets your Chrysler on fire! PM me if I can offer further Carter advice.

well it was a stock holley 4160 600cfm vacum secondaries with a heat riser choke... this new carb seems to be the same type of holley except it has an electric choke... i had a thermoquad on the 74nyb, it was stock and was great i even prefered the sound that it made, if anyone knows what im saying...
you and steve should band together to fight the evil holleys as he hates them too, and when two knowledgable sources deliver that kind of scour it must be true.
I really was looking into getting something different, like say an edlebrock with a little more cfm 650/700, but thier cost at the moment is very prohibitive, and as the car sees daily use with the high gas $ and the juggling of quite a few other problems at any given time... this carb is realitively cheap comparitively, or will be when i get to pay my patient buddy for it... 175 for a 250 carb isnt bad in my book.
Thanks for the input, and the more advice i get the better equiped i will be to tackle this.

If the throttle isn't returning all the way back to full closed, you might need to adjust the throttle cable, just don't adjust it too far, else you might not get full open when u floor it.
