I replaced worn original, but un-cracked, Campy pulleys in a beater Super Record rder with basic Shimano replacement pulleys, and shifting improved noticeably.
I had bought 2pr of the the Shimano pulleys for maybe $12? Then discovered I can buy a 10-pair bag for $22-$28/bag. A nice 10pr bag is now on the way, so for less than $2.50/pr I'm set for a few years of pulley replacements. The Shimano pulleys are black, not Campy gray, and they have "SHIMANO" molded into the plastic, so they won't pass muster at your next Concours d'Elegance, but they do the job.

Crikeys! I paid $24 for my bag, but Tree Fort has a price match for $19. Foiled again!

Then check the position of the jockey cage return spring, there are a few options, make note and try the one that helps best.
This is assuming there is little or no play in the mechanism.
But that Spring orientation....
