Title: Need Jetting Help With The DCNF's
Post by: DKK Ted on July 18, 2013, 00:54:35 am
Like the subject says, Haven't  played with DCNF's in years, until now. Motor is a 82X94, Web-Cam #100, heads are 42X37 wedge port. Need a started point, Idles, Mains, and Airs. The DCNF's are 42 Berg Specials W/short Type III manifolds. Any idea's?????  :-[  ;D

I'd start with 55 idles, 180 airs and 145 mains.  Make sure you have F25 emulsion tubes.  The idle may be a little fat, but you can adjust that accordingly.  It should get you pretty close.

I used "DCN's" but this thread might help  :)

try the same combo as idf's would be jetted. this seems to be a good approach in my book. the emulsion tubes are indeed F25's if memory serves me right.

some notes of what I got from the web because I have the Berg Specials and in the 1776 that I'm building I'll use them. I didn't checked again my notes, just copied and pasted here:

i assume the airs are too small. but i can work as a good starting point. you may need to go bigger in air and mains, the idles will be big too, but you'll have to see for yourself the exhaust color. 55 or 60 must work. 50 will be too small for the big engine.
