I had some side draft Webers rebuilt by 'professionals' years ago. They fitted SW kits, and after many returns for stumbling at acceleration, and having the float levels progressively increased with no effect, I took the car to a real expert who stripped and rebuilt again with genuine kits. He found that the plungers on the accel pump diaphragms were short by 5 or 6mm.
Funny, it ran OK after that.
