I just spoke to Cal at Lares. These guys know their stuff. He thinks the check valve located behind the hi-pressure line is stuck, because of improper bleeding procedure. He said to take line and fitting off, push valve a couple times to free, and bleed by starting from center, and turning wheel one eighth turn each direction and then further each way until air is bled out. I will be trying that this week. Thanks for the replies, will let you know how it works.
