Duel 44's on a 701 61x top and bottom

[S&Ssuperjets]

It seem to not have as much snap as with the single 44 . It has 120 pilot , 140 main And 2.0 n/s .The springs are silver not the dull I think that is the 95 gram . with a sport port home job on it .Any imput on the jetting ?:banghead:

B-Pipe? Go with Factory Pipe's recommended jetting, but start out 2.5 richer on both, work your way down. My bet is you'll end up with their recommendation.

Factory pipe doesn't have specs for dual 44's on a 61X superstock engine :wink:

Your jetting sounds much too rich IMO. What are your screws set at? Try setting all the high speed screws all the way in and see if it runs better. Just try it for a few seconds, so you won't blow it up if it's too lean (I don't think it will be but you never know).

it sounds very rich in my op
i have never set up 44s on 61x cases but if i was to i would have gone for about a 110 high
and about 17-19 psi popoff

with the X Cases, I would tend to think you would get more out of a single carb setup ( that what the cases were designed for) than duals....
