We don't use DCNF carburetors, not sure if any club member does.

i think most of the members uses twin Dcoe or Dhla...

Or PHH40s like is the favorite in Japan.

Or Weber DGV, which is a favorite in USA and Australia.

DCNF weber's are much like an IDA or IDF weber. they are a dual throat synchronous downdraught carb. I have a pair of 40DCNF's i want to try on an A-series at some pont. As for jetting i would reference the calcs and charts used to determine the jets used in DCOE webers.. I think it would give you a good starting point or baseline.

Also an added bonus for there use, would be on LHD B110 models, i reckon they would clear the brake master cylinder.
benny

DD,in Malaysia most ppl uses DCNF(performance) or DGV(Spirited Driving)..
For racing or drifting,we use DCOE or DHLA or Solex... :)

Benny,y dont u use twin side draught??
Coz they cant clear the brake master cylinder??

all of his are RHD, I'd say it's an exercise in alternate performance possibilities. And why not, they're a compact little jigger that packs enough punch for Ferarri
