: Emulsion tubes are perforated brass tubes that sit below the air corrector jets. They do the initial mixing of air and fuel in the carb. The F7 for the DGVs is a bit richer than the stock E. tubes. The F7 should make that primary to secondary transition a little smoother and give perhaps a small increase in power.
: 65-80BHP huh...I have my doubts;)
(I don't have any doubt...no way.) I've been told by experienced Weber DCOE tuners that the LAST thing you fiddle with is the emulsion tubes, change ALL the jets through a range before you start swapping those out.
Maybe the same holds true for the DGV series, the tubes do the same basic thing in all Webers. Read up on the theory and tuning in one of your chosen manuals and you'll get much better results than just reading numbers off the internet...even from me!
