LS120 stalls when hyd engaged.

[ponyboy123]

Hi all, Still messin round with the LS120 I bout last year. Now a new problem. Engine starts decent and runs decent but when I engage the hyd pump, the engine bogs down considerably and when I try and operated the hyd levers it tries to quit with the least bit of use of hyd force. What is up with that? I am finished going over the engine and all seems fine so next step is the hyd system, which I know very little about. any tips or sugestions? Thanks all.....

Could your aux hydraulics be engaged? this will load the engine down a fair bit.
