Lombard information needed

[PES+]

I have a Lombard 50s Woodlot Wizard 3A I believe

I need to know how to remove the sprocket I think they are threaded but I have never removed one before

I never had a Woodlot Wizard but the Comango was left hand threads, 9/16" nut. Maybe it is just a left hand thread sprocket.

Does yours have the Power Products engine or Tecumseh?

All the 3 series were pre tecumseh buying out PP so it is a PP

Tecumseh bought out PP in 57 and the 3s were all made before that as far as I know
