Set screw is still in.. the first thing i checked was the mbc. im leaning towards the bov still leaking somehow.. im getting pretty pissed. just checked the wg and the diaphram is spotless and added a second spring in the wg to see if it would give a raise. no difference at all. I can tell something is wrong by the sound of the spool isnt a whistle anymore. and now since i filled the tank i heard the wally255 sound like it was priming while it was running... ???
