[@mathewboyd3746]

Hey Gary, we've install hundreds of those exact China made IDFs. Both 40IDF and 44IDF's too. Never had any problems with using them in 5 or more years. The only issue lately is we've had the accelerator pump diaphragm seal leak on 40IDF's we recently ordered in two different batches. However, the batches of 44IDF's we've been buying had no issues with leaking at all. We solved the problem buy installing a new diaphragm and tightening the screws a bit tighter than previous. We often down size the venturies on 44IDF's or upsize on 40IDF's to suit the 1776 type1 motors and 2056cc Type4's. Otherwise very happy with brand (or no name brand) you have demonstrated

[@VWJawbreaker]

That’s awesome to hear Matthew! Glad to know others have had good luck with them as well. I figured as long as they were bench tested and cleaned first they should be ok!

[@mathewboyd3746]

[@seanlyon2989]

Ive had a couple of no name eastern carbs, you need to watch out for un marked jets with odd sizes, and poor assembly , but by far the worst is 'Zink Rot' or 'Zink Sickness' where the metal casting starts to crack and crumble, usually around screw holes or the fuel spigot. Humidity and/or cold seem to be the cause.

[@VWJawbreaker]

Pretty sure I said it in the video, either measure the jets and verify or run known jets. Haven’t seen anything to do with the rot before on many different carbs but I’ll keep an eye out for it. There’s plenty of humidity here in Florida.

[@battyboomfatty]

This is a great video, really informative. I've read good things on a few forums about these carbs so looking forward to finding out how they work for you. I've noticed they do 40 and 44s as well which might be good for the mild build I'm planning on going for.

[@VWJawbreaker]

I have seen the 40, 44 and 48 IDF’s and 48 IDA’s as well. Several others have posted they’ve had good luck with them. On the message boards you’ll read so much negative because people don’t want to give them a try.

I think those are the same ones I had on my 2387. The only problem I had is they would not stay synced. And couldn’t get each venture to read the same. One would read 6 and the other 10. But at full throttle I was happy I have a video of them running on my page I up loaded

[@VWJawbreaker]

I had the same issue on a set of Spanish Weber 40 IDF’s, one barrel was higher than the other. Look into the throttle shaft and butterfly’s. Sometimes if the carbs are old the shaft can twist over time and cause one butterfly to be more open than the other.

Hi Gary, Any reason you use brake clean over carb clean? I was leary buying a Chinese Weedeater clone carb till I got it. I identical except the throttle butterfly spring was too weak so took the old one off the old carb and it worked great. Wasn't that easy due to removing the butterfly out to change it. But for 10 bucks online it was a win for sure👍

[@VWJawbreaker]

I used break clean because that’s what I had on hand. I thought I had some carb clean but oh well. I bought a knock off carb for my chainsaw a while back. Same as you, had to swap one or two things and it’s been working great for a whopping $12. Couldn’t go wrong.

[@ShooterMcgavin6]

Haven’t watched it all the way through but shit it’s Chinese we’ve all scene the handy work of the chinese

[@ShooterMcgavin6]

Man I’ll be honest I was a little surprised! I’d like to know how it lasts in a few years. The metal the Chinese use is a lesser quality but if we can spend 1/4 the money and get a decent carb then I may come back to air cooled. But I’ll be honest the price of a used Honda Subaru motor and adapter vs a 2110cc I’ll probably build this bug Honda. It’s cheaper and more reliable with more horsepower

So I have what looks to be pretty new dual 40s knockoffs on my 1776 and can't get the carb on number 2 to adjust properly. The idle mixture screw doesn't change anything. I have had the carbs apart numerous times and I understand the adjustments, but still have the same problem. I've cleaned them many times as well. Can you please give me a direction to go, as I'm kinda stumped now, thank you

[@VWJawbreaker]

Since you have it narrowed down to cylinder 2, check the idle jet to ensure it’s not clogged and blow out that circuit with compressed air very well with the idle jet and mixture screw removed. Next check to make sure you don’t have a vacuum leak on that cylinder. Check valves because that could cause that issue as well.

[@Fastvw1]

I have used F2 before in the race car. and i have a couple of cars with f7's did you say those were 48's My street car has a set of real ones on it. according to some one at redline they don't work well on VW air cooled engines. I don't have an issue with mine but it did take about month to get them just right. BTW you do know that the venturis are not the same as 40 & 44's due to the bore size of the carb body

Hey man, next video we will go over everything and install them. I just looked up what I wanted and found a seller that had more than a 100 reviews.

i think i might still have my paperwork on mine I'll check and see, if so i can post the link Im sure its the same place on ebay the packaging and the variety of linkage parts gaskets were all the same even the price

HEY GARY , I'M NEW TO VW BUILDS AND STUFF BEHIND YOUR ENGINE YOU HAVE YOUR FUEL LINES CONNECTED TO A SYSTEM WHERE IT LOOKS LIKE YOU CAN ADJUST THE FUEL PRESSURE ? , DOES THIS HELP ? I'VE HAD A FUEL LEAK SINCE I BOUGHT THIS LAST MONTH , AND YESTERDAY THE GARAGE HAD A BIG PUDDLE SO I PUMPED OUT WHAT I COULD . SO I HAVE TO REMOVE A LOT OF STUFF ON THE DUNE BUGGY TO FIND OUT WHATS UP , YOUR THOUGHTS !! THANKS AGAIN ALAN

[@VWJawbreaker]

Yes, the gauge is a fuel pressure regulator to keep the fuel pressure for the carbs no more than 3psi. Where did your fuel leak from?

What distributor did you go with for the dual carbs? Did you get one with the vacuum attached

[@VWJawbreaker]

I’ve been running the cb performance Magnaspark and love it.

[@Golden-ui5um]

I've just recently got back into VW'S, had a bunch when I was a lot younger so I'm basically relearning everything. I have a 2110cc in a 63 baja, 110 cam, slightly better than stock DP heads, SVDA distributor, merged EMPI exhaust, and used 40 IDF carbs which I believe to be these clones. Engine idles perfect and good WOT but off idle to 1/4 throttle is terrible. Surges and stalls until I get rpm's up and or more throttle. The crossbar linkage looks ok except for the bolts on the lower end of the heim joints, one attaches close to carb and the other is about 1 inch longer. So geometry looks good from left to right on both sides of linkage but different angles from front to back if that makes sense? That being said I'm not sure that would throw it off enough to make the carbs open slightly different at part throttle but something is definitely not right. Another issue I'm having is the vacuum ports don't seem to have enough vacuum to advance the distributor. It's running from both carbs to a T and then to the distributor but has zero effect on it, only advances mechanically. I apologize for the long novel here, you seem to know a heck of a lot more than I do! I've swapped out the distributor but haven't tried mechanical advance only. Put the 34 pict 3 carb setup that was on the car originally before I rebuilt it and basically ran the same as far as part to 1/4 throttle. What could you recommend for a good throttle linkage so I can at least eliminate that problem? I'm having a lot of fun and I'm determined to get this thing dialed in, any advice would be appreciated. I guess I should mention that the mains are 125, air correction 200 and idle jets are 55, not sure what emulsion tubes? Thanks again

[@VWJawbreaker]

Glad you’re back into VW’s! Well, that stumble could be a couple of things. Ensure valves are adjusted correctly, no vacuum leaks at the heads or carbs, throttle shaft areas. As for linkage, I really like the CSP center pull linkage. Best one I’ve used so far. You’re jetting sounds pretty good, you would need F11 emulsion tubes for dual carbs. Here’s a great article on jetting www.aircooled.net/vw-carburetors-jetting-102/ I’d tend to look at the accelerator pump and pump adjustment.

[@Golden-ui5um]

@@VWJawbreaker thanks for your input, I adjusted the valves yesterday for the first time and checked the float levels and idle jets as well. I'll check for air leaks, that makes sense and could also be the reason I'm not getting good vacuum from the ports off the carbs for the distributor. I used the stock style metal intake gasgets cause that's what I had, those things never made sense to me? Would paper one's work better between intake and heads? I'll check the emulsion tubes and maybe get some weber jets in case the ones I have aren't accurate. Did you ever use the jets that came with the cheaper carbs?

[@VWJawbreaker]

@@Golden-ui5um for dual carbs I’ve had better luck with the paper intake gaskets vs the metal ones. Not to mention the metal ones are a one use only type of gasket. Without having a proper gauge to check the jet sizes, going to Weber brand jets would be a safe thing to do. I’d still look at your accelerator pump adjustment, there shouldn’t be a ton of threads showing. Back then off, then slowly add a turn at a time until it accelerates properly.

[@Golden-ui5um]

@@VWJawbreaker I did look at the threads on the pump, the nut is cranked way down on the threads on both carbs. I'll reset them the way you did in the video and get some better manifold gaskets.

[@VWJawbreaker]

@@Golden-ui5um the pump adjustment could be most of your problem if they are cranked down that far. Try that first and move on from there.

[@JParkes43]

Where can they be purchased?

[@VWJawbreaker]

eBay, Amazon, etc.

[@JParkes43]

@@VWJawbreaker ok. But any ideas of the to the exact set

[@knockout818]

Why not run the f2 emulsion tubes? Curious

[@VWJawbreaker]

Something with the way the holes are in the other tubes and size of the holes makes them richer and lean out in different areas. I’m no expert in all that, I’m going off of what the experts say, like John at AirCooled dot net for example. F11’s for dual carbs and F7’s for a single dual carb.

[@tommiesmith3369]

The F11 is great for most Dual carb setups with 36/37 or smaller vents . The f2 may play well with a 48IDF . Each emulsion tube as specific characteristics based on O.D. Of the tube and how much fuel is in the galley - along with location of air inlet holes which dictate richness of the mixture provided to the secondary venturie- float height and emulsion tube also dictate when main jet stack takes over . As a gauge about 25% of throttle position is idle jetting A decent portion of this also gets a little adjusted fuel delivery based on mixture screws. Mains are in full control at 75% to 100% full throttle Everything in between is controlled by main,emulsion tube and air corrector . Not exactly on the above but is good gauge for idea
