Chris,

Weber DGVs are progressive-linkage 2-barrel carbs that have been used as
conversions on Z-cars for many years. It's 4 x 34 mm. By my calculation
that's 92% of the venturi area of the 2 x 2 inch setup.
I'd suggest if they're capable of putting out the horsepower a Z-car needs
that they'd be fine on a Healey--if properly set up, which these may not be.
Having said that--since this is what's different on the car, it's
undoubtedly the problem.
I wonder if the secondaries are failing to open up.
