Wasp flashing pk 50 fl

Good afternoon everyone.

I would like you to help me as I am learning the mechanics of wasps.

I have a 1991 wasp pk50 fl2, for some time I have been spending €€, pinasco 102 cylinder, simonini exhaust, hp4 magnetic flywheel.
I recently bought a 24 inlet and dellorto 24 phbl carb.
The wasp works much better with this carburetor but it has a idling, I adjusted the idling screw and it didn’t work, I already changed the low end gigler and it didn’t solve anything?

Can you help me?

Thanks for the help
