OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Question On Scott Bonnar Cylinder Mowers Scott Bonnar 45 Cutter Clutch and Thrust Pad

Hi,
I have just replaced the clutch body key and thrust pad following the notes on this forum with regards to its position i.e. there should be clearance between the thrust pad and the inner cone.
When I pulled the cord to start the engine, I can see it is disengage and looks ok but as soon as the motor runs, the clutch engage the cutter when clutch fork is still in disengage position.
I'm not sure if I did something wrong on re-assembly or is there something else that I should replace.
One thing I also suspect is there should be a space between the clutch body and the engine as I can see some unpainted part of the shaft near the thrust pad.
I have attached some photos and hopefully this will assist in problem diagnostics.
