Pump is a 2006 Reed. One problem is when pump is engaged after warms up it will pump one cylinder fast and other will pump real slow, taking 5 time as long or more to complete stroke on that side.doesnt do it 100% of the time. I’m assuming this is in control block not hydr pumps tandem 125’s. It’s at a hydraulic shop now. Any input welcome.

a competitor got excited to buy a used T-A nice pump but has the exact same quirk in the stroking.

guess its been through three shops without a proper dianostic. my wild guess could be a blockage in the control block, but iam really interested in the outcome.
