I'll double check the lines and isolate, I did re-flare 4 lines and the 3/32 jaw in the bar was a bit worn, so caused some frustration.

On the MC, it is a 1 1/32" (got sucked in by the price, $17.59). One wouldn't think 3/32" would make that big a difference, and wouldn't the line pressure be higher with the smaller bore? Could it be a matter of fluid volume? Could the stroke be less on the 1/32" MC?
