Weber F16 Emulsion Tubes

"Given that Weber jets don’t particularly wear"
I have some antique idle jets stamped EW. These idles do not perform where they should on the Shankle Automotive diagram. They lean out. The new ones above and below where these antiques are perform as the Shankle scale says they should. I tried cleaning them, gently, but unsuccessfully. I suspect corrosion or gunk or a different grading scale.
So I think they can "wear out."
Don't buy those F16's. Contact Keith Franck and buy some VF tubes to try out. I want to find out how well they work. Venturi Fountain Tubes You might like them better and can let us all know. Thanks in advance.

I'll just share this here (DCOE Idle jet chart)
I made this table and chart while working to tune my 1750 with DCOE 151s I've been experimenting a bit again and resurrected it. It might be of interest to folks here. Rather than just do what others have done I read up a lot on how the webers work, what circuits are used when and general...

Im using the VFs in my 59 2000, which has a 2300 FNM engine. Definite improvement over the F16s, which is why I have several leftover F16s."Given that Weber jets don’t particularly wear"

Keith has sort of discontinued the VF, although his testing continues. He now offers, I think, three different tube designs, depending upon Manifold vacuum at idle and ratio of Venturi size to cylinder volume.
I was thinking wear as in getting gunked and crudded up, which is the only reason I can think why they would lean out on me.
The whole VF tube thing must have something going for it. But when I was trying to fathom it, I couldn't get a clear answer before Yahoo dropped their website for Keith's newer site hosting.
I am running F34's which perform for my 1700 conversion now. Finally got it sorted with Ben and Richard Jemison's help.
I fiddled with them with a Zeitronix O2 sensor and feel confident I won't burn my exhaust valves now or carbon my rings. I don't claim to have your racer knowledge, just fiddling knowledge.
FastRoadCars.Co.Uk gives you both, a good price, quality and new parts...........One man show not big business Pierce Manifolds or cranky like the guy in Auburn, WA.

That's very interesting but how did you decipher which VF tubes to use?
The question is did they smooth out the 3000 to 3200 transition area. That's the area that gave me trouble. It would help if I could understand why Keith thinks these work better than F series other than magical voodoo. Do you understand Don?
