No worries AA - There's actually quite a lot of old balls talked about CS/VP installations like the 'oversquare' myth and all sorts of bizarre wives tales.
As I keep preaching, read and inwardly digest the POH or, failing that, corner the local mechanic in the bar and ask him some questions to find out how the thing works. Each type is different and each is worthy of a read up to avoid poor operating practise or - in extremis - damage to the engine / prop.
Didn't mean to get all snappy n'all!
