this one for a while.

My theory : when steam (air) is leaking past Orings somewhat 
continuously (even tho there seems to be enough power to keep the 
mechanism moving), there is no distinction between valve events and air 
flow.  When there is no leakage (either piston Orings or slide valves) 
the distinction between steam events becomes noticeable.  The oversize 
cylinder bore allows Oring leakage.
