1980 Carb Replacement

[parsok]

Brad,
I read your documents and they are quite excellent and much appreciated to be sure!!

Do you know if a 4-2--1 exhaust from a '72 will fit this engine?

Thanks

[124JOE]

on the head YES and the down tube will have to be the 2 pipes into 1
they have 6 bolts


and happy b day

The 1972 exhaust manifold will have 4 studs.

Parsock: I think you might want an FI 4-2-1 system (and that would be the six-stud mainfold-downpipe joint) for block height reasons.

Weber used to be made in Italy, now made in Spain. The other brand is made in China.

Yes, indeed... There are a number of geopolitical reasons to prefer a Spanish Weber over a Chinese EMPI;
is there any engineering reason to prefer the EMPI?

Can't say definitively since I've only seen/have Webers and never seen/picked up an Empi. Manufacturing tolerances, quality of materials would be a guess, but hey their drywall, structural steel, and paint for children's toys are all top notch.

Hi,
Have you done your carb replacement?
I'm in exactly the same situation, I've bought a 34ADF + 1800 intake manifold, but I'm new at this and like to know if it's "easy" to do and have some picture of the engine (to see how it fits, what to remove..).
Thank you.
Guillaume

I have to say this, I bought a carb from card direct, piece of shit from day one, yes I said that . I just got the empi from mark and it works like a champ, and yes pay a few more bucks but at least u don't got to fight with it, I would not get another from carb direct, I know it not there fault

Any carb, whether it be a used unit, a rebuilt unit, or a "new" unit should be taken apart, cleaned and inspected prior to installation. Even if it came straight from the factory it can have tiny particles of casting flash or grit from the production process that need to be cleaned out. It's also not uncommon for the carb to need adjustments with regards to the minimum and maximum choke opening as well as adjustments to the position of the primary and secondary throttle plates. Unfotunatly these specification are hard to find even if they were ever published.

Jim, IIRC your problem was with the secondary throttle linkage. Problems do occur from time to time, even with brand name manufacturers. It could be a real problem with the linkage, the carb could have been droped at some point, or its workings are just misunderstood. Although I don't think I'd call it a piece of.... Its good to hear your problem is solved

You know it isn't their fault, but you wouldn't get another carb from them, it's a piece of sh*t, whatever. Maybe you dropped the carb or installed it wrong, or perhaps overtorqued the secondary by misadjusting the throttle arm. When you install a D series carburetor on a car made for an A series, you're changing geometries. You had a lot of people here try to help you out, and you shit - yes I said it - shit all over everyone with posts like this. You crap all over the car, put it for sale, blame the carburetor, blame the vendor, blame this and that.

You bought an EMPI to replace a Weber for god's sake. That's all kinds of wrong.

the EMPIs come from the factory, tested and flowed with alcohol. Many I've installed have not needed one bit of adjustment either with idle speed nor mixture. If you look at the dyno comparison video I posted of the EMPI HPMX and Weber IDF, you'll learn that EMPI is still doing r&d on these carbs. They've improved the venturi cluster on the IDF to alleviate the flat spot off idle and ended up making a bit more power too. Weber isn't doing r&d on carbs, they've moved on to FI. Weber has licensed a couple of mfgs around the world to produce their carbs now and EMPI is one of them.

Sorry, I was ranting about the lousy, ungrateful attitude and not the carbs. FIATs have Webers is all I meant, in the traditional sense. Nothing wrong with EMPI.

Unlike the Holley-Webers the EMPIs aren't made of play-doh.

Lol, give it up, No I did not drop it,over toque it, I installed it, plain and simple,it was the secondary that was messed up, and btw, I thanks people for trying to help. It hard to explain how the secondary would open and then just close by itself, so yes I got. Empi and it works like it suppose too, ,would u like me to send u this weber carb so u can investigate , just let me know ,. Thanks for being concern over my attitude, and I hate junk! I am not a mechanic,but I do know how things work or don't work

[bradartigue]

So you didn't even try to return it? Just knocking everyone else about your misfortunes? LOL you've got issues.

It will be returned, I have had problems with this from day one, it prolly has 50 miles on it , yes I have issues when things don't work and when it should work, it not like there was a loose linkage or any thing, it a defect,even my mechanic looked at it but I already orderd a new one , thanks for caring
