Make sure the spring on the F vent is strong enough as it has to hold the F vent closed when both RH fingers 2 and 3 are closed. If the spring tension is too light, the F vent can get blown open on the low notes from D downwards.
Due to the design and heavy gauge flat spring on the F vent on S20, S20c and S40c cors, the RH 2 and 3 fingerplates also have to be sprung heavily enough so either of them can counteract the F vent's heavy gauge flat spring and hold it open. It takes some balancing to get it right and so it doesn't feel too heavy under the fingers.
Pro level cors have a much more complicated forked F vent mechanism which is lightly sprung (relying on finger pressure and being in good regulation instead of on spring tension to close it).
