weber 46 ida jetting
 

I dynoed my 2.8 twin plug to check some jetting changes. It's running rich 10:1+ from 4100 - 5600 rpm. I'm currently using 140 air correctors and thinking of going up in size. Not sure how much to go up before I would notice a difference. Any suggestions?
150 mains
140 air correctors
F3 emulsion tubes
60 idle
36mm chokes.
Thanks.

This is the set-up PMO recommended for my 2.8, and it has been working extremely well for me:

Venturies: 36mm
Main Jets: 160
Idle Jets: 60
Air Correction Jets: 180
Emulsion Tubes: F3

(9.5:1, S-cam, SSI and dual out)

I had 180 air correctors in there, it was suggested to try the 140's. I'll drill the 140's out to 160 and try that.
9:1 I think (p.o's best guess) runs fine on pump gas
