I picked up a 10hp Lauson (Tecumseh) as a spare for my 65 Sears Suburban tractor. I haven't gotten into it yet, but assuming it probably will need new valves, piston, rings and gaskets, I thought going the overhaul kit route would save me some money. I guess I'll just have to order the parts individually.dgraham225 said:no, not that i have ever seen. what specifically is the problem with your engine? is it an issue that may be easily fixed or are you just doing some preventative maintenance?
