I thought I knew but I don’t. DCNF fit a bug?

[oldslow]

What carburetor/carburetors do these filters and manifolds fit?

Those should fit a Weber DCNF carb, They would make for a nice Vintage look engine.

I think Earthquake has it right. More specifically, they look to fit DCNF-12s (non flat-top). Note the recess in your air filter base and the air horns built into the carb top on the -12s

If you go with these do yourself a big favor and get the Berg linkage if not running type 3.

And keep in mind parts for these carbs add up fast!! Just be ready.

Or ditch the air filters and try dual bug sprays or Rochesters. Dare to be different.

I have a stash of DCNF carbs in 40, 42, and 44mm sizes.

[oldslow]

Ok great, Thanks!I would like to put these on the wife’s ‘64 convertible
Am I nuts?
Berg linkage is a must

I've run a single Weber 40DCNF on my 1835cc DP engine since back in 1976.

The carburetor has NEVER been off its manifold since then, although I did replace a leaky accelerator pump diaphragm once.

I have some DCNF’s on my ‘65. They kinda fit, and they do work good, but I would never do them again. Next time the engine comes out, eBay clone IDF’s and a CB linkage kit is going on.

Mine are the Racetrim/DDS style manifolds, and they are about the exact same height as Berg manifolds. I made the center pull linkage, but I should have used the Berg linkage. I also made the filter bases to use standard IDF size filters, so they clear the body better than those big square style.

The worst part about the DCNF’s in a bug is the forward facing idle jets. Guys think IDF jets are hard to get too......you ain’t seen nothing till you try to get the 3/4 side out on a DCNF. The front cylinder mix screws are no picnic either.

Way to much screwing around, parts sourcing, fab work, and rigging. You will be way farther ahead with standard IDF’s and a good quality linkage/manifold kit.

There is a reason the VW world went away from these and stuck with IDF’s.

I feel like a ghia, type 3 or 4 would be a good place to use these carbs, some short manifolds in a type 3 looks like they would be a better fit under the lid than IDFs, no?

Need replacement filters for original Kadron aircleaners? WIX #42087 is a perfect fit, as is Napa Gold #2087!

[Brian_e]

They are about the most ideal solution for T3's. The manifolds are short of course, but they are pretty straight, unlike the IDF T3 manifolds with 2 90deg bends in 3".

They would be just fine in a ghia or bus.

They are neat carbs, and they run very smooth. They are just to big of a pain in a bug when IDF's are so easy.

They work great in my Speedster replica.

In a type 3, the filters are pretty small, to fit under the lid, and I didn't like it, intake air temps were very high (70° C +).

I dunno, man..
It does take some fiddling to get the whole layout thing sussed with DCNFs.
Had to stare at mine and mock them up a couple times before i had it all right.
That you can flip them on the manifold is golden.

I’m thinking Gene Berg was right on this one.
I’m able to tune the transition hole out of mine easier than with my IDFs.
Looking at the mild-mannered high-end cars the DCNFs came on originally,
It makes sense that they would strive to get them to work well IRL.

Yeah,
You can buy a kit and stab some IDF clones and gave success easily,
But wasn’t it Aristotle who said
“All fine things are hard”
?

Sure,
If a customer was paying me to install a set of dual carbs,
The choice is easy.

Would i trade my DCNFs for a set of IDFs now that they’re dialed in?
Nofucking way.

What would a set of rebuilt DCNF 40's with gene berg manifolds and a CSP linkage be worth. I have a set I may sell as I ended up going with IDF's instead.
