When my Old Blue starts behaving badly, eg: slows appreciably, skips a  beat 
or two,  hangs, etc. I cycle some air compressor fluid through it.  First shut 
off air and bleed system. I pull the hoses from the cylinder. Pull  one of 
the lines at the compensator and squeeze in about 4-5 decent squirts of  fluid 
and re-attach it. Then turn on the air and cycle so everything flows  through 
the valving. I catch the discharge in a coffee can while holding on to a  
flopping cylinder hose. Sometimes have to do this process twice.
