I have a 9020b in the shop that is doing some strange things, it is an intermittent problem. After starting and running at full in standard mode if you hold the stick boom or travel over relief it will bog down the engine and stall if you hold it long enough. If you switch to heavy mode it will do the same but then sometimes will smarten up and work perfect for ten mins. It is acting like the pump is not cutting back and is taking too much power out of the engine, but is intermittent . Has anyone had the same troubles??
