Did you run the Alpine with the rebuilt carbs before 'parking' it? If so,
the gas left in the carbs turned to varnish over the years and is 'gumming
up' the works. You might (Very Likely) have to replace the float needle
valves, as they have to work absolutely perfectly, or else the car will run
much as you've described. Beyond that, simply driving it a few hundred miles
may clear the rest up.
Did you set the mixture per the manual? I'd recommend against leaning it
out too much. With no lead in the gas, burning valves is easier than ever.
How about the spark plug wires? They deteriorate with age, and screw up
perfomance greatly.
Most Strombergs need to be bushed by now to eliminate the vacuum leaks that
result from wear in the carb body (no bushings originally) around the
throttle shaft. But since yours has been off the road for so long, the odds
are that the wear is not that much greater than the rest of us, so they
should still be tunable. New throttle bushings are available from Sunbeam
Specialties. You'll have to have the carb bodies machined out to accept
them, and the bushings machined to match the throttle shafts. (This is on my
list of winter projects)
