Im running my beetle on the 40dcn and while it needs tuning from time to time, ive found the perfect fuel/air mixture and its running really well (tho i am running it a bit lean) Though i do think its a bit wasted on my ittybitty 1600 engine. Its not wasting too much fuel.

I was thinking of selling it and 2 smaller ones, but now that i know what they are worth i think i'll keep it anyhoo.

umm... blue74l... can i have a copy of the aforementioned webber pages as well please🙂) asterope@iprimus.com.au Muchly appreciated!
in the beginning, the universe was created.
this made alot of people very angry and is widely regarded as a bad move.

I have two of these type of carbies that I'm getting ready for the 1914, I'm building. What I am after is the hex linkages, so I can set them up on my type one engine.
Has anyone out there got any ideas or can let me know where I can buy some linkages to suit.

I have one on my cabrio with a standard 1600cc and extractors. It certainly gives it a bit of go, and a lovely weber note on decelaration.

Only critism would be the lack of a choke which means it runs like crap until its warmed up.

I got the carby rebuilt by a carby shop in Sydney for $90 including the price of the kit.

Cheers

Steve

Very popular carb for single carb applications once. You should find you can fit the "shroud-type" linkage. I seem to recall the guys at VolksPower in Melbourne were fans of these, might be worth a call.

I've got a 40DCNF and it has a choke mechanism that uses a cable to operate it. Had it on a 1776 in a beetle and it ran great......motor gone now and the carby is just sitting in the shed waiting for a new motor.....😀

The "problem" with DCNF's is the bowl " I believe"

Apparently the have a tendency to flood while going round corners.

Gene Berg sold modified versions for years. They were VERY popular in the 60's and 70's

I have never run these carbs
I ran a Progressise for 18 months.

People said they were THE worst carb - but i reckon it was great.

Bite the bullet. Run the carbs. Have a good go at making them work and make up your own mind.
