Chinese IDF copies

[vdubrookie]

does anyone have any input on these carbs as far as reliability & fit & function? Easy Peasy has a video out saying the are built pretty well but need to be calibrated(throttle plates adjusted & jet sizes checked) but that the basic carb is decent. Just wanted some more opinions on this. $120.0 per carb vs. almost $400 is quite a difference but I also know the old saying "you get what you pay for".

I have roughly 500 miles on mine now. Im running a 1600DP , CW crank, Engle 110 and I had to jet down to 45's on the idles , and 125 (could stand to go to 120's) on the mains. I'm extremely happy with them for the price. in the long term we will see how they last , but right now they do what they are supposed to.
if you buy them you will need to completely go through them and clean them. while they seemed really clean there was some junk in my idle circuits. do your initial setup as described in the dual carbs thread and you'll be set. this being said I can tell you out of the box i have had to do similar to Holley xp carbs as well as edelbrocks to ensure they are good to go... NOTHING is ready to go out of the box

and for the snarky... yes you get what you pay for... but no reason to be a dick about it

vdubrookie,

Try searching on YOUTUBE for videos using "IDF Clones".

Lots of info and reviews.

Some of them may even be unbiased, unlike many on here.

GOOD LUCK and STAY WELL!!

It depends on which Chinese copies you’re talking about? I have a dual set of 44 HPMX’s on a car I put on maybe 10-12 years ago, and they’ve been great. The Chinese Weber’s that are assembled in the US have issues. I’m with Dave, and am not going to be the guinea pig for the $90 eBay IDF’s.

I have been able to get them to work on several motors now.

No real issues. STandard re-jetting and tuning that is needed with any carb getting dialed in.

[Ohio Tom]

I just ordered a pair of Maxspeed 48IDFs.
$245.

I will report my findings once I run the motor and get dialed in...

[Alstrup]

EVERY Weber needs work out of the box. Spanish or Chinese. That said, now we know what to look for, the quality IDf clones can be made about as good as their Italian fathers. There are still some sub quality copies out there. But in general it can be done.
Now we just need someone to step up and make some quality Dellorto´s - Ahh, well, I´m affraid that´s not gonna happen. The Weber copies won that battle

Agreed. I love Dells'

Hard to find thou...

[67rustavenger]

Love Dells too. I have 2 working sets. 36 and 45's.

The funny thing about these China IDF threads is. That every time they come up.
Someone posts that they are cheap (Yep!) and not the best quality.

Even funnier is the fact that these same China IDF detractors. Often run HPMX carbs.
Gee, I wonder where those IDF clones were developed and manufactured?

China!

For the idfs, there are 2 different large companies producing them. The Fajs and many others that have the original style roll pin in the accelerator pump arm through the throttle shaft are made in the Jilin China Factory. Some of worked well, and some have had issues.

The Carburators that have the flathead stainless screw in place of the roll pin in this spot such as below are made at the unrelated different business factory in Taizhou China. Lots of people have used these and worked well. I have ida's from this factory and they are beautiful. Both factories have many "names" or brands attached to them that mean very little. Similar to other stuff that looks similar, different brands, made in same factory type of deal.

The Stainless screw idf clue:

I have run the 48mm FAJS Ebay carbs on my Road race Beetle. They ran OK at first, now they have been giving me problems with the throttle shafts binding up. Should have stuck with the Webers.

Jpaul, those look really nice.

Dare I say: Better than a Weber inside...


Never had a problem with throttle shaft bearings.. they do need oil you know..
All bearings need lube. No matter what brand...
