That's the  dilemma of lot's of cal lookers. Using new parts that works well or use good old looking parts with variable results.

I vote for DCNF. Looks good,  more adapt for street use than IDA and it is possible to use air filters.

Same vote than j-f ... 42dcnf is better choise ( for me )..
I sold My IDA for build 42dcnf ..

With Ramflo fliter !

For a drive I would use DCNFs they work better than any other carb and still make power.  Driveabiility is what it is about.  At least for me.

I still have the 42 DCNFs at my dad's if Frank is interested. They have CB K&N style air cleaners, no velocity stacks or linkage and type 1 manifolds. I remember having to pound the crap out of the passenger side engine compartment on my blue and white 67 to get that carb on. It still hit when the motor rocked. They have been sitting for 15 years so they will need to be gone through.

Nice Headwork Jim !!! I would go for Kadron's. Simple, Parts available. One thing i did in the past was to get rid of the idiot aircleaners. Have some machine guy turn me some rings for the top of the carbs/ and large conical  K&N filters. And this combo SUCKS air. Wish i have kept them.

On a buget and still want performance...kads.
Didn't a few of the DKP cars of the early '90's have kads?  ;D

Kads are too small for that cam, IMO.
If you want to be different, get a pair of 32ndix's from a 356 mounted on DDS or Race-Trim, or... manifolds. They would flow the air needed for a 1800cc...

Steve Hollingsworth modifies the dcnf's to let fuel into the place where the screen is normally.  Then he trims away that awful tail-like inlet.  That way you don't have to cut up the car.

I'd say the forerunner.  The earliest reference to an IDM I have found is 1958, and they were discontinued in 1964 when the IDA came out.  The footprint is the same as IDA.  Jet stacks and floats interchange.  Nothing else.

Frank's 1915.

This is a 1776 with the DCNFs, a DMS crank, Magnum gears, CB cam similar to a W140 and stock heads w/dual springs that I got from Darrel a loooong time ago. I built it when I was 16 and it has less than 10 miles on it. Suffice to say it didn't run very well. I'm going to recam with my old W125, port the hell out of the heads and find some 44 IDFs.

Now that weare talking about carbs...............when building an engine for our cars,the most (?) use
the weber 48 ida carbs(and in callook land these are "THE" must have carbs).
But there are also weber "idf" carburettors.
Now my question (is this a stupid question?  ???   ):what is the difference between these?
Can/will somebody help me out?

IDF's are a pain in the a** to adjust in a bug. Perfect for a bus though ;)


Title: Re: Carbs, carbs and MORE carbs....
Post by: Rennsurfer on April 29, 2009, 00:13:00 am
Yep! They ARE a pain for most people. Hence why I'll hopefully end up with a set for my 1915cc. Because I'm used to doing things the difficult way. It is how I rotate.

That's why 'Weber Windows' came in to play.  I run 40mm Dells.........I dig 'em.  IDA's are the shiz are far as looks and performance go though.

Everything! IDA's were made to be a race carb, IDF's were more geared towards street use. As far as I know, pretty much the only thing that is interchangeable are the jets.


Title: Re: Carbs, carbs and MORE carbs....
Post by: marc1951 on May 21, 2009, 02:56:55 am
IDFs have better progression circuits which makes them smoother when driving in traffic. The IDAs were made for wide open throttle, balls out racing so the part throttle smoothness is not so much a concern.
Personally I prefer the IDA, but then I always have my foot into it.
Anybody running a Holley Bug Spray has experianced the lack of progression circuits. You can get them to run well but it takes patience getting the right gap between the main jet mixture and the idle mixture.

having run both for years.....

The IDA's: on the surface, it's hard to come up with logical reasons to run these on a street car. Not that they run poorly (even in 2 prog hole setup), because if they're tuned to what your motor wants they are fully driveable. But it's the non logic that makes the 48's such a must have. If you have IDF's and you go for a ride in a hot car with IDAs, after that ride you'll want a set. They sound incredible, they pull harder all the way up, the engine seems to have an edge it never had with IDFs. It's a whole different game with IDAs.
The IDFs are good carbs for bus or a car you'd drive everywhere. I'd say start with 44IDFs if you buy them, as the 40 IDFs seem so soft on everything. Nice thing about IDFs is the air bypass circuits you can adjust (given you can even get to the screws to adjust them though). IDF's are a step up from Kadrons, that's the best way I can describe them. They pull nicely at low and mid rpm, good on freeway. Get ready for lots of swearing when you drop a cylinder because of idle jet plugging.

Now thatīs were the Dellorto DRLA comes in. Lovely carb with idle jets on top as the IDA.!

i'm so curious about DCNFs cause nobody use it here in Italy...the most use IDF o DRLA..( maybe cause 36 & 40 idf & DRLA were easy to find on ALFAROMEO 33)
can someone talk me about DCNF? i see that are very used in States... are they older than Idf i think..right?
what cars mounted it?
thank u !

I think DCNFs came on Ferarraris of Alfas.  I don't know which came first.  I have both a set of 44 DCNFs and 42 DCNFs currently, but I am using the 42s because they seem to be more driveable.  They don't make as much HP which makes sense as they are smaller.  They are very smooth with no flat spots from idle all the way up to over 6000 RPM.  Mine are Berg modified with Berg manifolds match ported to Berg heads.

Post by: nicolas on May 22, 2009, 19:59:36 pm
my experience between 40 dells, IDF's and DCNF's is that i like the DCNF's a bit better.

the IDF's and certainly the 40's are a bit underrated and i have to disagree with Jim. they are a very good carb for engines under 2000cc and will work great on a street/strip engine. sure idles clog up and they need some finetuning, but i think they respond very well and are with a bit off patience quite easy to keep in tune and good working order.
but i have to say i would rather have 40 dells over 40 idf's... they seem to have more power in them and just have that silky smooth transition from idle to mains built into them. the idea that dells are better then webers could be only my personal perception and be completely a thing between the ears.

so then comes the dcnf ( i run 42s) and they are just the ticket for me. they fit nice in a type3, look bulky like a type3 engine and just run great. recently the only thing i have noticed is just a little stumble when hitting the trottle in lower rpms. just a small hesitation when i hit the gas. but that is probally a jetting issue.

Allen,

Great post!!! It had me laughing. The only thing about EFI is when you're on a long cruise and something electrical goes.  You can cripple a carb motor to the next repair stop.  With EFI you are dead in the water if electrical issues arise.  Otherwise, EFI is obviously far superior in all other circumstances.

Good to see you post.  The 67 looks great since the new paint job and refurbishing!
