Lets Install Those No Name Chinese IDF Clone Carbs on my Volkswagen! Big Fail? Part 2/2

[@tommiesmith3369]

It’s all about jetting that’s it. Those could be great for your setup. I don’t think valve size is a gauge to work with - of course it is but reality says you can get many varieties of setups functioning on the same valve size . It all goes back to where do you want your power band . A large venturie will be soggy on the bottom end and awesome in the higher rpm range . And vise versa for a smaller vent . The venturie effect is squeezing the air through an opening where it speeds up on the other side - this aids in port velocity for lower rpms and also vacuum to pull fuel out of the bowl. But can become a choke at higher rpms. On a big vent you loose all sorts of port velocity on the bottom end but gain the loss of a “choke” on the top end so it flows and flows. All about drive habits and just what you want to achieve. IDAs can be the best of both worlds if setup correctly. 44s with 36vents is a strong all around setup . I ran 44s with 32vents for ever such a good setup for my little motor . I think the board with flow is not functional if the information is not consistent when comparing . I also think carbs are easy - need to do a video of what is what and why things are happening when they happen.

[@VWJawbreaker]

Well said sir! That’s pretty much what happened, large vent on this setup absolutely flew mid through upper rpm band but was soggy down below. Of course I needed to up the idle and main jets some more. However, I don’t race this car and street drivability is important for me. I ended up putting my 44’s back on for now. I know it could be better than what it is but all around it’s great how it is. I figured I’d see how these perform and for the price I couldn’t go wrong. IDA’s with 36 vents would be perfect but then I’d be out cnc machined intakes 🤷‍♂️ Sometimes it’s just best to leave things alone but then that’s no fun 😂

[@GoodOldMike]

That jam at 11:56 is pretty dope. 😀 Still watching and curious how this is going to work out.

[@VWJawbreaker]

I have to agree, not to mention the dudes music in general is killer. Need more tunes! It worked out ok if I would have remembered what size intake valves I had when ordering the carbs. The venturi is too close to the intake valve size so I lose low end and it idles higher than I would like. Top end is no joke! Need smaller venturi for these carbs and it’ll be perfect. But that’s a story for later down the road.

[@zas5892]

Both of my 48 setups on both of my Motors are totally streetable they idle perfect at 9:50 and there are 9 1/2 10 1/2 to one motor and they are all day all night on the street no problem Gary put the carburetors back on they'll work

It’s a pretty stout 2054 with fk8 cam, 1.4 rockers, 10.0:1 compression. I could have put smaller venturis in it and gone from there on the rejet, decided to put the 44’s back on since I do so much driving. I could have gotten these to work decided not to.

Hi, Gary, have been watching your videos on youtube for quiet a while now.. Very informative ! I am in the process of building a 1835 engine for my '73 beetle. Have the engine ready so far, and just pulled the old engine, to transfer all the cooling tins and other bits and pieces. Tried to do a mock up with the new manifolds and carbs, and there is a lot of interference between the manifold flange and the cooling tin. So much, that it is pretty much impossible to get the manifold in. How did you modify the cooling tins to make that possible ? Any tips would be greatly appreciated !

[@VWJawbreaker]

Glad some of the videos have helped ya out! As far as the head tins, you’ll most likely need to modify them a little at a time to get the manifolds to fit. Usually you’ll modify the interior “flap” that goes between the spark plus. You might be able to bend things around a little to get the manifolds to sit properly.

[@Mtbeaver9]

I have a question why we don't use f2 emulsion tubes in vw? what does the emulsion tube do?

[@VWJawbreaker]

That can be a long answer but the short of it is, the emulsion tube is used to maintain the air fuel ratio at all speeds.It consists of a well with main metering jet at its bottom. The jet has holes on its sides.It is in communication with atmospheric air. Initially air is drawn through the holes into the well and fuel is emulsified.

[@kenshelhamer9816]

I think your vacuum signal is lower with the bigger venturies and you need bigger idle jets.

[@VWJawbreaker]

Yea sir, you are correct. Still with the bigger idle jets it won’t idle well.... best to drop venturi size and rejet.

[@Slick56]

Ahh Dual Carbs... as soon as you said 48's I thought about port velocity and jetting. Some one should be able to supply you with vents or have a shop spin some out on a lathe. likely you will need to jet up on the main and drop the air a little. You can get bigger vents for your 44's or have your current vents bored out to say 38mm you will need to bump up the main and drop the air jets some as well. Idle jets may need a bump up too if you cant get it to adjust with the mixture screws. CB has that update kit for the IDF'S that changes the secondary vent to a spray bar and it comes with new vents and jets. but that kit would kill your bottom end too. I found stock idf44mm carbs on the street are just right for me. I run very similar engine to yours. A set of CB ultra wedge ports with bigger intake valves would do the trick too. I have a sweet set of gene berg 52's that I would love to run but would have the same issue as you right now. manifolds linkage vent size ect. Sad to say for me the next step is fuel injection or turbo or both to get more power and keep drivability with out tearing my motor down. thanks for sharing I am also not an expert but enjoy and appreciate what you are doing.

[@VWJawbreaker]

Like you, I’m not an expert. I’m just trying new things and bringing everyone along for the ride. You are correct, the vents are too big to idle and for low end. She screams hard up top though but not very streetable imo. I did find a set of smaller vents for these carbs, that’ll be a project for another time down the road. Thanks for the feedback, hope you have a great week.

Oh and ps, for some reason I thought my heads had 44mm valves, not 42’s. If that’s the case these would have worked better.

[@VWJawbreaker]

Actually that’s not true at all and this engine is no where near stock. They were better accordingly but the venturies were too big. Personally, I don’t like running single IDF’s or the 32/34 carbs. I would need a lot more info before I could recommend a carb.

[@doginu]

You needed larger main jets at least 2 sizes, the F11 emulsion tubes leaned it out even more. Just buy some 40 mm Venturis/Chokes for your Webers

[@thisisschennss8291]

Thank you for showing these off to the community, I'm sorry the carbs didn't work out for you, I know that you have to pick your battles on what upgrades you want to make work. I had the same issue with 48 IDA's prior to installing 37mm Venturi. The way the 48 IDF's were out of the box you would have needed at least a 70 idle jets, and with the large Venturi and FK8 cam your idle might have settled in around 1200'ish RPM this is fine and well for the strip but is just not particle for a driven street car.

[@VWJawbreaker]

100% correct, this would have been perfect for the strip but not practical on the street. They did great on mind and upper rpm, just no low end torque and some drivability was lost. We live and learn, we wanted to see what would happen and now we know.

@@johncollins5552 I haven’t touched the apron yet, it’s something I’d do if I ever need to replace the apron but don’t want to hack it up just to make it removable.

Of course you have other vw projects... Those carbs could go that way... Just a thought... I have AS 40/35.5 heads (I think from CB performance) Feeding the fuel is dual 40mm Kadrons. They work, but my fuel mileage sucks. Any suggestions? Keep up the great work brother!!

The beat place to be honest, grab a Webber book. Bench setup is the most important, from there is jetting. Read whatever you can find.

The top end loved those carbs, I just lost some low end and idling.

[@felixlafuente9714]

Try this: one, close all air bypass screws. Second, Fuel level up and third, smaller airjets will put you there. I bet

[@VWJawbreaker]

All air bypass screws are always shut on my carbs. They ran good but the venturis were too big causing a higher idle rpm to maintain a vacuum through the idle circuit. Air jets aren’t being utilized at idle, only at higher rpm.

[@felixlafuente9714]

@@VWJawbreaker good day! thank you! Sorry, yes, you are right on idle! Do you think Bigger idle jets wont help it?

[@VWJawbreaker]

@@felixlafuente9714 no need to be sorry, we all have different strengths and weaknesses and we’re better as we all learn together! Larger idle jets would only deliver more fuel and make it run richer at idle. Refer back to the pinned comment on this video, Tommie did a great job going through some explanations.

[@richpeacock5768]

Jawbreaker sounds a lot like Mellow Yellow when she is cold. I feel the need to do some adjustments on Mellow Yellow now because she is definitely not right.

[@VWJawbreaker]

Maybe she just needs some more tweaking. Not running chokes is a sacrifice we make though.

[@stephenbrown5580]

Curious to see if these are a decent upgrade option in the end. Any thoughts on playing a bit more with them or an upcoming video in the foreseeable future? Love the channel, BTW

[@VWJawbreaker]

Well, since I screwed up by ordering these with a bigger venturi, the low end performance was blah. I could have spent another $100 and bought smaller vents but decided to sell them instead. In all reality, and my driving habits, 44’s with 36 vents are a better choice. With that said I know a few people who have had great success with these carbs as long as you bench clean / set them up. If you need a dual carb kit, I’d recommend buying a kit instead of piecing it together.
