Well, I am somewhat confused. I learned that soft mounts were only of value
at low rpm. In a racing application, the higher revs cancelled out the value
since the jet, variable venturi, etc were operating at a larger opening and
the fuel was moving thru the system much faster. It was kinda like not
spending a lot of time on the low speed jets. Once launched, the carb never
operated in that range again until finis or backing off the tow vehicle. I
know of those who bolt up solid their Weber DCOE's--a carb notorious for low
speed frothing without soft mounts. What is the new theory? Have anything
to do with state-of-art fuel compounds (y'a know, the fuels that eat rubber
fittings)?

Subject: Re: High Speed fuel starvation
I too have been chasing a high speed miss on the Duke. The Duke's problem
seems to have been cured by balancing the front rotors and mounting the carbs
with soft mounts. I surmise that the fuel had been foaming so badly that
although fuel pressure looked good, there was nothing in the bowls but foam!
(Which if I could get an internal combustion engine to run on I could make
millions...)
I won't miss that miss...
