My forgotten Bolens which my grandmother purchased in 1972, sat in a barn, slowly sinking in the ground for nearly 15 years after a screw loosened from the carburator throttle blade and beat the piston into submission on the iron Tecumseh engine. About four years ago I decided to bring it back to life. The cylinder had prior been bored .020 over and luckily it was in good shape. I had to replace the (piston, rings .020 over), rod, head and gaskets along with a couple used tires. The valves survived but had the exhaust valve guide replaced at a machine shop because it was sloppy. I have the mower, tiller and dirt plow attachments but just do garden tilling with it now. When I was cleaning out the barn, I just couldn't scrap my Grandmother's Bolens and made a good winter project back in 2015. It will always be "Grandma's Bolens".
