Probably can be made to "work" but pointless, and never as good as a properly set up dual manifold with carbs opening in sync. A complete waste of time and energy in my opinion. A properly setup dual in my experience has better throttle response and better mpg than a single on a stock manifold, plus the obvious more power and greater urge in the higher rpm range.
Probably setup includes addressing the ignition curve, and if it's a 8BA type, deep sixing the loadamatic. I learnt from JWL's dyno testing that two carbs want less total timing.
Any re jeting and power valve sizing for 97 style or opening vacuum for 94 style needs to be looked into aswell. Jet sizing normally ends up damn close or same as stock. The rule I use when buggering about with carb jets is, too far from right is wrong. If you think it wants much smaller or bigger jets, something else is wrong. The word much used here would be used if you pulled out (of a 94) 51 jets and plunked in 55 or 46, that's to far from right.
In my experience.
JWL's book confirms I've not been barking up the wrong tree with the carbs
