Did run drive and cut fine. I believe valves need adjustment or bad decomp on cam. i blew up the starter gear trying to turn the motor to start it and since gave up. Sitting in garage since. Rear tires have dry rot from sitting. Newer Battery but its dead. 17.5 HP Briggs Hydrastatic trans. I know for a fact it runs cuts drives perfectly fine as I used it last summer. Very clean too
