The lawn mower blade was for checking clearance for fan and radiator. Had to use what was handy as the old Farmers did back in the day. Still had to use a 3/4 inch spacer to clear the harmonica balancer . About 1/4 inch clearance between fan blade and radiator. Six blade fan solved over heating problem. I Trashed the electric fan. Ol’roy looks good riding around Atlanta.
