DCNF carbs
sam P:
When I was running 42 DCNF's on my car, I did notice some hesitation under heavy cornering. You could smell the fuel from floading in sharp turns. Besides that they ran fine. But I never looked into the problem so maybe it was something that could be solved.
They're nice carbs but they look so small in a type one engine bay!
Zach, could you close the engine lid when you ran 'em on your type 3?
Here's a pic of my (messy) engine bay at the time:

I just had a thought - didn't Claudes buggies manifold mount the DCNF's so the were 90deg to the crank ???
They werent DCNF's, they were a pair of Weber Progessives.
And yes, I could (still can!) close the engine lid. I used Berg manifolds and short aircleaner assemblies. IMO, they are the perfect carbs for a type 3- they are low profile, so your intake manifolds & air filters arent too short , the barrels are close together so the intake path has a straight shot to the head (unlike a Weber or Dellorto, check those out sometime! :o), you dont have to cut anything to get them to fit, and they are ugly little carbs, much like the type 3 engine itself! :D ;)

DCN's came first. I think the DCNF's were introduced in about '75. In a bug you have to trim the edge of the compartment to clear filters. I used Berg 42 Specials in my type 3 and I think they are the perfect carbs for pancake engines because of the short profile. Ive heard 40s have the wrong circutry, and 44's are just as good as 42's. For driveability and mileage, I dont think there are better carbs for a big motor.
could anyone tell me what's wrong with the cirutry of the 40's? I've read something about the progression holes being the wrong size? But could you get around that problem using a smaller idle jet? or to go even further to close the holes and dril new ones? I did a little research about the berg specials and most of the thing can be done to a 40 as well. I bought a set of 40's to replace my IDF's, just because I find them more period correct..
what needs to be done to get the best out of the 40s? its for a 1641, if that changes the game a bit..?
thank you,
glauco
