I presume you and others who choose to use the Weber downdraft carb
are aware that there is an adjustment available for the accelerator
pump? This hesitation you describe might be cured by
setting the pump adjustment to feed more or less petrol upon movement
of the throttle. As I recall, there are two holes that one can select from
regarding this adjustment, one of which gives greater movement of the
pump mechanism. Would be interested in results.
