Just wanted to let everyone know I found a small fuel leak at shut-off valve under fuel tank(packing was loose) repaired bled lines and it seems to have fixed the problem. It must have been sucking air.
Just wanted everyone to know that I found a small leak at the shut off valve under the fuel tank once I repaired and bled the lines tractor seems to run great with added power. It must have been sucking air hence the lack of power. Thanks to all.
