Looking for a good set of four (4) F16 Emulsion Tubes for DCOE carbs.
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"
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 just found this remarkable work to read for your interest:
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...www.alfabb.com
The answer is to install a wideband and determine if you are rich or lean in that area, by how much and over what rpm range. Selection of idle jet, main jet, emulsion tube and fuel level will all have an impact but until you accurately define your problem you are shooting in the dark. In my experience you don't have to have a transition problem if you have a good ignition system, a wideband and an understanding of how Webers work.The question is did they smooth out the 3000 to 3200 transition area. That's the area that gave me trouble.
