I have an old Sears lawn mower as pictured above. Im planing to try and build it into a pulling tractor. Yes i know its not a cub cadet so its not thee pulling tractor to use. But I just want to build something with what I have laying around. Its got a 10 horse flat head Briggs and Stratton in it. Im looking to get a diffrent block to punch out .030 over as I found an aluminum piston for it already. Looking for a high rpm flywheel and connecting rod along with stiffer valve springs. Any help or ideas on where I could get any of those would be much appreciated. Thank you. Looking to try and get kids at college in the machine program make a cad file for the flywheel and connecting rod and get them to make it out of billet.
