aboard wazzbat and I am sure that we will be able to help you with your enquiry. Deejay (Darryl) is our Scott Bonnar addict here and I am sure that he will offer you help with both pictures and what he has done to his Scotty.
The model that you quoted is a 33 as the 45 came later after Rover bought Scott Bonnar. We do have the parts list for that model in the parts list and manuals area of the forum.
As to the motor that Scott Bonnar used, the Tecumseh engines were one of them. I would assume that the tank or complete motor was taken from one of the first 45 model Rover/Scott Bonnar's mowers that Rover made after the take over.
I hope that this is of some help but once Deejay sees this post he will jump in and reply with some more information.
Once again
to the forum.
