Hello everyone. Are the 40DCN and 40DCNF idle jets compatible? Thank you.

Many small parts in Weber carburettors are identical and used in several models.
Strange enough, this is not the case with the idle jets in DCN 40 and DCNF 40:

The original numbers are often shown as 74401. and 74405. (followed by the size
number, e.g. 055)
