Help what have I done? I tossed my iron intake and Q-jet and installed a Edelbrock Performer and 1405(which I bought from a fellow member and a good deal too).Two weeks before the transplant I did plugs,wires, cap,rotor,breather,pcv,fuel and air filters.The truck ran fine if you like bogged out tanks! The intake was cleaned up and I rebuilt the carb,I'm no expert but I've done this a few times before.I used a full rebuild kit plus a whole new choke kit,and jets, needles,springs and a new accelerator pump.Now itz like Edgar Allen Poe is under my hood! The pinging won't go away! The further counterclockwise I set the timing the worse it gets thru the entire driving range.And I can't turn it clockwise enough, my vacuum advance hits the firewall.Did I screw up the carb? Is there something wrong with my distributor I've double checked and I'm sure I put the intake in right side up! The killer is my mileage has improved 30% and I can squawk my 33"Michelins!

did you hook your vacuum advance to the timed port or the non timed port. about all i can think of right off hand is it is hooked to the non timed port, therefore it is getting vacuum at all times to the advance and possibly causing it to be to far advanced at all times.

have you checked your timing with a timing light yet? if so what is it set at? also if you did this, did you remember to unhook and plug vacuum advance when you set timing.

also when you changed jets, did you go back to the stock jets or did you go a step or 2 leaner on them?

eric

ps: you didnt say but i am guessing with that carb that this is a 318 or a 360 we are talking about

NOW you see why I always say that folks should stick with their iron factory manifold and Qjet. The iron manifold flows every bit as well as the Performer, and the Qjet works better at steep angles than the CarterBrock...


Have you put a light on it to see where the timng actually is?

Pull your spark plugs and see what (scalded white) color they're burning. Sounds very lean to me...

And, do the unlit propane torch trick along all the manifold gasket edges and carb base gaskets, you may have an air leak that is contributing to you incredible mileage, and the lean condition...

 

[oldmanram]

Right - did you check the timing with a timing light ? - It could be that you just got the dist. gear a couple teeth off when you put it back in, and can't get the proper range without hitting the fire wall.

 

[Dodgebreath]

Sorry for the omit,yes itz a 360.Timed port(passenger side).Yes I used a golf tee.I can't use a timing light cuz itz so far off the markings itz impractical. I did not pull the dist,however my wires are rotated one position from "normal"which makes me think itz not in right,thus preventing the proper settings?(Thatz the way she came to me)

 

[IntenseImages]

well the easiest way i can think of at the moment to solve this, and oyu are gonna hate to hear this, but i would pull manny back off, bring number one up to TDC and check/relocate distributor drive gear where it belongs.

then put everything back together and start over with the timing setup.

this way you will know it is put together right, i think this will go a long ways towards solving oyur problem.

BTW, if oyu cant use a timing light, then there is really no reason to set timing by pulling vac advance.

You reckon you could explain this to me?

 

[Smokey]

Well, you can always do the "blown finger" trick...
Pull the number one spark plug, and push your finger into the hole, have a friend (or use a remote starter switch to)bump the engine around in small increments, till compression blows your finger outa the hole.

Look at the timing mark on the damper... it should be quite close to "0" TDC, and you know it's on #1 compression stroke, er'else it wouldn't have blown your finger out... Turn the engine by hand (wrench, whatever) so that the timing mark is at 10 degrees advance.

THEN, track the #1 wire back to the cap, remove the cap and see just where the rotor is pointing.

That will give you a good idea whether you can "fix" it by simply rotating the distributor; or, whether the distributor is back in "out-of-whack" far enough that you need to pull and reset it.

I would try this, to get the timing right, before I'd pull it back apart.

essentially you are chasing down a vacuum leak.

doesnt have to be an unlit torch even though this works well, i personally use spray carb cleaner for the same thing.

what you do is you start truck, let it get warmed up, then oyu take the torch and open it up so gas is flowing but do not light it. you then slowly run torch around intake manifold and carb base. if there is a leak it will suck propane in through leak and engine will either speed up or if you are using carb cleaner for this it will probably cause engine to die when you find the leak

[Dodgebreath]

Thx gang.I guess i'll check for leaks first,but I'll be real surprised if there are any.Then go to the distributor.It may have to wait today I'm running my Ragtop (69 Satellite 440-4bbl-727 3:23sure grip) And no offence Smokey,but the Dodge Gods I worship put Carter/Brocks on 440's.Rochesters belong on Chebby's

 

[Smokey]

Hey, I was running MOPARS when those carbs were still CARTERS, and the ram intakes were really long. Carters're a great street and drag carb. But, no matter who makes the Rottenchester, it is still better at high angles than the Carterbrock. I personally prefer Holleys.

And don't ignore the timing advice. All the carb dinking and distributor twisting in the world won't get you past a tooth-or-two-off-problem.

 

[chrysler300le]

to find out if your distributor drive gear is off pull the distributor out after you get the engine to TDC. The slot in the drive should be pointing towards the very front intake manifold bolt on the drivers side. It if doesnt' then there is a chance that the timing chain jumped or someone installed the drive wrong. Its pretty hard to pull the distributor drive up in the vehicle with the intake on. If the drive is ok then put distributor back in place and put in a position where you have the most movement to change the timing. Rotate your wires if needed.

Okay so after 8 hours on Saturday I still have ping! Tried the propane nothing.Checked the distrib found it to be installed at what I would call 180 degrees from where it should be? Meaning with #1 @TDC my timing mark is under my truck.Cleaned up distrib,reinstalled it.Found vacuum advance canister hits oil pressure sending unit preventing full range of adjustment.Changed that.Set it up and the ping is still there. I checked vacuum its @ 21.5" Road test shows it runs fine accelerates well it just makes this embarassing rattle .and to answer a previously skipped question I put the carb back together with the same size primaries and stepped up one size on the secondaries.Which should make it richer,I've ordered new jets to go back to original.HELP ME PLEASE!

is it a ping, or is it a rattle? a rattle could be a whole lot different things than what causes a ping.

[Dodgebreath]

I 'd say ,hell I don't know anymore.It's not a rattle like metal on metal.It's gotta be ping cuz I can vary when it occurs by changing the timing.Can I rotate the plug wires one more position and turn the cap to get more/less advance? Also my exhaust vapour on intial start-up blows 'sooty' deposits,kinda like diesel.

well i was thinking something along the lines of a collapsed lifter, this could also be changed by changing timing.

the odds of oyu being able to get your timing correct by just changing towers with the wires might work but i wouldnt bet on it.

best way is to get a timing light and make sure you are right where you think you are. also make sure that the outer ring on balancer hasnt shifted making you think timing is somewhere it isnt

as far as black smoke on start up this would signify a rich condiditon.

[Dodgebreath]

Well, with the plug wires rotated one tower which is the way the truck was when i got it,I can't rotate any further cuz the hold down is at the end of the casting recess in the distributor.I guess I could file that protrsion off but the canister is almost at the firewall now.thx Kev
