Webber carb set up question
 
:Just ran my 3lt on the dyno and it is showing a rich spot at about 3 to 4.5 k
what do i need to change it is running F3 emulsion tubes 160 mains and 170 air correctors. Would changing the emulsions help my rich spot?

Not a jetting expert but F26s should help out. I'm assuming you have normal auxiliary venturis and your float levels are correct.

Yes i am running 34 venturi , what do the numbers mean on the emulsions is higher richer?

emulsions are all over the place with their numbers. F26 is stock. a step up to 180 air will lean out the top end, if it's still a bit rich up there.
