: Hello, am new to tractors and am looking to maybe buy my first. I have found an old Massey Ferguson 202 "Workbull". I haven't bought it yet. It has a Continental gasoline (4 cylinder I think). It dawned on me over weekend that a motor this old was made for good ole leaded gas. Given that this probably has NOT had the valves changed over (stallite??) for unleaded gas use, should it seem to me that after prolonged use, I might expect the valves to deteriorate. If so, how much might it cost to transform the valves, and if you go that far on a tractor that is probably 30 years old, would it be then prudent to put rings in, then overhaul the bottom end?? Or might I be worrying to much? I have never owned a tractor, and read a thread here just last week about someone purchasing a tractor that had water in crankcase etc...I would rather pay 4 times as much and purchase new than purchase an endless headache. : Thanks for any thoughts : Richard Work engines like tractor and truck engines, unlike consumer products tended to have hardened valve seats and stellite valves as standard equipment for a longer than that tractor is old. Heavily leaded fuels were a WW2 innovation, before the war gas was mostly what we'd call unleaded. But adding lead made less quality oil stocks burnable as engine fuel. So older engines don't expect lead and may end up fouling plugs with too much lead. Gerald
