Not actually today but yesterday. A while back I made a barn find. It is an Allis Chalmers ( Model 610 I think) ride on mower made in the 1970's. It had seen little use even the underside of the deck still had paint on it. Problem was it had not run since the early 1980s and just sat there. Well after cleaning out a mouse nest and replacing the ignition system and a few other minor repairs. It fired up. Ran with lots of blue smoke. I figured I would just let it run nothing to lose really. Blue smoke stopped so I took it out for a run. Blue smoke turned to black smoke. So replaced the air filter. I even mowed a little with it. I think maybe this winter I will repaint the hood and the upper part of the deck.
