That's correct. The Solexes weren't designed for use with a vacuum advance.

Yep. And put a fuel pressure regulator ahead of the carbs.

Not necessarily. That's pretty normal behavior for Solexes. There's no choke
valve, so when you put the pedal down, the intake ports see atmospheric
pressure.
Roll on the power, don't just hammer it, unless you're above 3000 rpm.
