Got a free lawn tractor as a gift! Engine locked up!removed sp. plug, bathed garage floor in gas! Hmm.changed oil, new sp. plug, inst. fuel valve, some TLC, and mowed for an hour. seems ok. Man sez he bought a new one. He has a very steep section of grass, better than 45d! I told him to get an engine with pressurised oiling in engine. Sez he bought that kind. Keep old tractor. I sing:"On top of old Smoky" when i use it. Hello to my old friends here! 90 YOA, still driving, pickin the banjo, in good health, and chasing wimmen! Rusty Jones
