I rebuilt a hydro on my exmark hp. it is just a little slower than the old one and it feels a little less powerful. Before running the mower I filled the hydro reservoir and manually turned the wheel to remove the air from the system. Is it possible to still have air in the system. I drove it around my yard for about 30 min. with no change. It seems like it needs a little more bleeding. any help would be appreciated.

nevermind. it was very easy to rebuild the pump. after a few small adjustments; it runs great. I am willing to bet that most pumps can be repaired; however, most shops will only replace the pump b/c they are not true mechanics just parts changers.
